I really hate the whole Tesla angle of "technically we are not lying but we know people are going to mis-remember and misrepresent what we are writing".

Take for instance: > The driver had received several visual and one audible hands-on warning earlier in the drive...

What this means is that during this incident there were No visual or audible clues that a crash was about to happen

What they are saying is that while he was driving there was an earlier point at which the car did not crash, where the car gave a visual and audible clues. And you have to ask? Why the hell is that relevant? It isn't. They are stating it as a fact because they know some people will incorrectly claim that the car warned the driver prior to the crash.

With their eager to try to explain what happened why aren't they talking about what actually went wrong? Why did the car drive straight into a barrier. If their claim is that it was cased by the driver not having his hands on the wheel for 5 seconds, then they need to fold the company and give up trying to create self driving cars. That is Not acceptable of a self driving system.

The fact that the barrier was damaged intensified the accident, but that does not in any way excuse their system driving straight into it. And no, you can't get out of culpability by claiming statistical superiority. That's like a gang-member drying to get out of jail after killing a rival gang member because his gang statistically kills fewer people. Tesla has put a product in the hands of consumers, when it kills those consumers they need to step up to the plate and be honest about their fuckups, not just blame the drivers, blame the infrastructure and point to statistics.

Quite. Tesla is deliberately comparing their modern vehicle design & wealthy driver base (statistically one of the safest cohorts) with the entirety of the U.S. driving population. This is bad statistics: We expect Tesla vehicles to have far fewer accidents than the mean US vehicle per mile, because Tesla's are expensive modern vehicles with (relatively) wealthy drivers who can afford to keep them maintained & will themselves be in better health than the mean US driver.

Don't tell us how safe Tesla's are compared to the entire US driving population: Tell us how safe they are compared to equivalent vehicles from other manufacturers. My working assumption is that Tesla doesn't do that because it would be far less flattering to the 'A Tesla is totally safe, honest' PR boosterism that runs through every Tesla press release.

> Don't tell us how safe Tesla's are compared to the entire US driving population: Tell us how safe they are compared to equivalent vehicles from other manufacturers.

I'm having a hard time to find an exact number comparison, but:

- Tesla claims 1 fatality per 320M miles

Compared to

- A 2015 study of 2011 model year vehicles showed, for instance, Volvo XC90 had never been involved in a driver fatality (1)

- There are about 10K 2011 XC90s in the US (2)

- Avg. US drivers cover 13,400miles / year (3)

So:

- 4 years studied * 10K vehicles * 13,400 avg miles -> 536,000,000 fatality-free miles

This is obviously super hand-wavy, but I think it's fair to state as a hypothesis that Tesla could be twice as deadly as the safest high-end vehicles.. you'd need to design some experiment to attempt to falsify it to feel confident this is correct.

Eh, you can't cherry pick specific (model, year) combinations after the fact without overfitting. You expect some variation in deaths per (model, year) and by searching for the least deadly ones, you'll dramatically influence your estimate simply because you used a maximizing search instead of a broad survey of a-priori safe models.
Re:An Update on Last Week’s Accident by jakewins on Saturday March 31, 2018 @12:38PM (#16723957)
This is totally true, and I agree; I tried to guard against this at the end with the "I think this is enough to state a hypothesis, which would then need to be tested.." paragraph.

However - the same is true for 2009, 2010, 2011, 2012 model XC90s, and they are just one of 10 models that had no fatalities in those four model years in the study. I just picked that year and model to get one data point for mileage to compare; the other model years of XC90 have similar sales, so the same applies.

So, while you're right, I don't think it's an entirely useless comparison; it indicates there could be something here, which could then be used to state a falsifiable hypothesis, something like: "Similar cohort drivers would be safer in <one of these ten models> than in a Tesla.".

Re:An Update on Last Week’s Accident by emn13 on Saturday March 31, 2018 @04:40PM (#16725071)
At a minimum it indicates that Tesla's numbers do not seem exceptionally safe, even if you can't say they're less safe than comparable competitors either.

Given the low number of incidents, you probably want to be looking at something other that fatalities to get a large enough pool of incidents to reduce the impact pure chance; at least in addition to actual fatalities. It's not going to be an easy comparison, that's for sure.

Re:An Update on Last Week’s Accident by lettergram on Saturday March 31, 2018 @12:07PM (#16723822)
Probably should also note, that the average Tesla driver is likely male, has money (i.e. more risk taking), etc. Essentially, compare to sports cars as opposed to high end vehicles.

They we're originally advertised as sports cars really. 0 to 60 faster than any other car, etc.

You're going to have to explain to me how the wealth of a driver has any bearing on their ability to pilot a self-driving car.

Re:An Update on Last Week’s Accident by pja on Saturday March 31, 2018 @05:38AM (#16722563)
Firstly, wealthy drivers can afford to keep their cars in better shape and can afford better cars in the first place. Neither of these factors depend on self-driving technology.

Secondly, Tesla themselves makes it clear that their self-driving can't be relied upon to driver the car unsupervised - the driver has to be paying attention at all times in case the Tesla self-driving code decides to do something catastrophically stupid. Hence the same factors that correlate with driver attentiveness in the ordinary population will also affect the Tesla population. Wealth correlates with health correlates with better reaction times & general fitness.

The Tesla autopilot tends to turn itself off precisely in situations where driving is difficult and complex - which in turn implies that these human factors will remain just as important as they are in the general driving population.

(Of course it may simply be that the reason wealthy people have a lower death rate on the roads per mile is that they can afford cars that are safer in crashes; the above is my supposition, not evidentially backed.)

I agree with your general point, but you can't just join up 2 correlations like that, that isn't always going to work when there are other confounding factors (and there always are). Wealth also correlates with age which anticorrelates with reaction times and general fitness.

In case anyone's wondering, here's a simple example of 3 variables so that the first is positively correlated with the second, the second positively correlated with the third, but the first and the third have a negative correlation: simply take 3 independent standard normal variables, X, Y, Z, and define our 3 variables to be u=X+Y, v=Y+Z, w=Z-X. Then correl(u,v)=0.5, correl(v,w)=0.5 and correl(u,w)=-0.5.

Lower accident rates, or a lower percentage of injury or fatal accidents? I find it hard to believe 80 year olds are getting into fewer accidents than 40 year olds unless it’s because they drive less frequently.

Which would be fine for an insurer of course. Heck, even if they got into more incidents, but the incidents were cheaper, that would be fine for an insurer too.

And not all markets are equally competitive. Just because insurance rates differ doesn't mean risks necessarily do the same way. And let's not forget that while insurers are professional risk assessors that doesn't mean they're infallible either, or immune to other distortions (e.g. pass-the-buck subprime mortgage kind of issues).

What I'm looking for really is anything specific to auto-pilot technology to suggest that the safety benefits won't also be met, or exceeded, when extrapolated across the whole population.

All other factors taken into account, driving has become much, much safer in recent years, and is now safer than it ever was. When you start to use technology to eliminate driver errors in that self-same error-prone cohort, there's no reason to think that the safety dividend won't be even more pronounced than it is today.

If you want to link crash rates to wealth, you would also have to account for countries like Germany, that has a similar median wealth figure to the US, but a vastly lower motorway death rate [1]

It seems you can't both say 1) Tesla drivers are less likely to have accidents because they are wealthy and error-prone, and 2) Extending self-driving technology that eliminates basic errors to less-wealthy and/or more error-prone drivers won't have a net benefit on driver safety.

[1] https://www.sciencedirect.com/science/article/pii/S240584401...

Re:An Update on Last Week’s Accident by pja on Saturday March 31, 2018 @06:07AM (#16722651)
I’m suggesting that Tesla drivers are both relatively wealthy & /less/ error prone!

Clearly /if/ Tesla self-driving code is safer than the average driver then extending that to the general driving population would be a net good. But if the apparent safety is an artefact of the statistics due to Tesla cars themselves being intrinsically safer just as practically every other modern vehicle is a safer car than one built 20 years ago then extending self-driving to every vehicle might not be a net safety benefit

Likewise, if the driver cohort is different (and we know that it is different) from the general population & that cohort is required to drive the vehicle precisely at the times that the self-driving code can't cope which are probably the times when driving places the most demand on the driver, then that different in driver cohort matters: the statistical difference in death rates could easily be a result of differences in driver populations.

You can't tell from the data as given & the fact that Tesla keeps repeating the aggregate figures in their PR is suspicious frankly.

(NB. that paper you link simply underlines my point - In both countries, the lowest wealth quartile has a vastly greater death rate on the roads than the rest of the population. It doesn't matter whether Germany is worse or better than the US. If Tesla draws disproportionately from higher income deciles, then we should a priori expect them to have a far lower death rate than the mean. Quoting the mean as a benchmark to compare the Tesla death rate against is outright misleading.)

Re:An Update on Last Week’s Accident by Spooky23 on Saturday March 31, 2018 @11:08AM (#16723594)
Wealthy people tend to be older, which directly correlates to less impulsive or stupid behavior on the road.

People who buy a super expensive car have more to lose than some dude in a 10 year old hoopty.

Maintenance standards vary. We can presume that big brother Tesla maintained the car as they would have castigated the driver for not doing so. They are also the only game in town.

Re:An Update on Last Week’s Accident by fcantournet on Saturday March 31, 2018 @05:33AM (#16722545)
Statistically if you're wealthy enough to own a Tesla, you're also way less likely to have to drive when tired/under the influence for example.

All sorts of constraints are correlated with wealth that put you in way more risky situations if you're poorer.

There's lots of different kinds of crime, each very unique in its circumstances. Just try comparing the stats for securities fraud vs. drug possession, for example.

DUI is a tough one, people of all socioeconomic backgrounds like to get drunk, and people of all socioeconomic backgrounds like to drive. Off the cuff, I might guess that the numbers would show DUI to be the most egalitarian crime, actually.

We do? Is there a cite for that? It seems to me that driver of new luxury vehicles are disproportionately aggressive and unsafe, actually. Has this been studied?

Re:An Update on Last Week’s Accident by jacquesm on Saturday March 31, 2018 @07:54AM (#16722907)
The simplest argument here is that Tesla's are new vehicles, the total US fleet average age is much older than any Tesla on the road today and driver/passenger fatalities tend to be higher in older cars because they have fewer safety features.
Re:An Update on Last Week’s Accident by ineedasername on Saturday March 31, 2018 @04:41PM (#16725073)
higher in older vehicles

This seems intuitively that it would be true, but are there any stats on car age and accident frequency? Also where is the line on old? Vehicles made in the last 5-10 years will share most safety features, with all but a small minority of newer cars having some cutting edge. I'll admit I had been thinking of fleet age from the state of maintenance, but safety feature is a fascinating angle as well.. And the article you link in another comment was a fascinating read too, thanks!

Re:An Update on Last Week’s Accident by jacquesm on Sunday April 01, 2018 @01:59PM (#16729564)
For one there is the presence/absence of safety features (that one is obvious).

Then there is the actual design of the vehicles, cars that were made in the last couple of years fare much better in collisions with cars that are older because they are a lot stronger, and are better able to channel the energy of an impact to areas away from the passengers. Many newer vehicles will for instance shift the engine under the passenger compartment in a frontal impact.

Older airbags had 'best before' dates associated with the igniters being somewhat unstable and that reduced the certainty of them going off as they got older.

Then, finally, the bodies themselves, once cars start to rust you can patch them up but they won't be the same afterwards. There is quite a bit of redundancy in the body but it definitely doesn't help if there is significant corrosion.

Re:An Update on Last Week’s Accident by ajross on Saturday March 31, 2018 @07:58AM (#16722921)
Yeah yeah, I get the argument. The point was that you can't ding Tesla for "bad statistics" by using an argument that asserts "tend to be" without evidence.

In fact I personally doubt (i.e. I have no evidence and am not actually making this argument because it would be "bad statistics") this is true if you compare Tesla's to the BMWs being sold into the same demographic. Those "safe new vehicles" you're positing include a whole lot of crossovers and minivans driven in much safer ways.

It doesn't. But autopilot is only supposed to be used on the highway. Not in New York City. Not on dirt roads. On the highway. That's the easiest place to make a system like that work - adaptive cruise control and a simple lane follower go a long way there (I hope Tesla has something a lot more advanced than that). To compare stats on their limited use autopilot to the whole country is truly disingenuous.

One important nit: it isn't self driving. It's sometimes self driving.

About cohorts: how about this: young (thus inexperienced and more careless) drivers generally can't afford Teslas. So yes, wealth is an indicator for how accident prone someone might be.

Less rich people, less healthy, driving smaller, older, less well maintained, less safely designed cars in more dangerous/remote locations. That’s a bunch of factors contributing to safety or lack thereof. Vehicle age alone is a huge factor in safety. Even the likelihood the driver and passengers are wearing a seatbelt is likely vastly different between Teslas vs all cars on the road. All those factors add up.

But that’s not even the point. The point is that the numbers Tesla gave are meaningless. Tesla’s stats would only be meaningful if you compared them to similarly sized/priced cars of the same age cohort with the same market segment. The fact that Tesla compares its luxury high-priced large sedans to all cars and not its own segment is itself very telling. They have those stats, and they would use them if they were compelling.

The expectation is simple: value human life. Don't try to do beta tests and simultaneously market it as if it's production quality. Accidents happen, but own up to them; don't immediately and fervently insist that you were not at fault before the investigation even starts.

It may be easy to casually update software and break builds, but when human lives are at risk a healthy dose of conservatism is appropriate.

But you're right -- it's probably unfair to expect a SV company to prioritize anything over profits (we saw that with Facebook, right?)

Re:An Update on Last Week’s Accident by Arnt on Tuesday April 03, 2018 @05:22AM (#16743054)
I thought about this over the weekend. About that you want, concretely.

Tesla says their cars have drive past that spot 85000 times so far. So you may be asking for some testing that's better at uncovering problems than 85000 whitenoise test instantiations are. Or you may be asking to test, and test, and improve until the software meets the developers' intentions: If their intention is to improve safety by 40% (or 400%, or 40000%) then you may be saying they shouldn't release a version that's improved over the baseline by 20% (or 200%, or 2000%) because that still doesn't realise the design.

Seems a bit absolutist to me. You could equally well make the opposite absolutist argument that having inhouse software that's better than the current released is putting people's lives in danger by inaction/negligence/whatever. That fixing a bug or improving a feature confers a moral obligation to release immediately, lest people's life be put in danger which would be avoided by the new code.

This is by far the most important point in this discussion. According to this article (https://www.greencarreports.com/news/1107109_teslas-own-numb...), Tesla's statistics are deliberately wrong, and Tesla compared its Autopilot crash rate to the overall U.S. traffic fatality rate—which includes bicyclists, pedestrians, buses, and 18-wheelers.

You could argue that Tesla should be compared to luxury vehicles (which have more safety features), but even if you just compare their crash rate against U.S. drivers of cars and light trucks, the Tesla Autopilot driver fatality rate is almost four times higher than typical passenger vehicles...

Tesla always blame the "driver" (and publicly so, nonetheless) when they are killed by their "autopilot" (which is actually driving, that is fulfilling the purpose indicated by its name, despite being not very good at it...) -- either directly, or by carefully stating misleading statements that are both technically correct and incredibly dishonest in the context of both the events and the surrounding text.

This is probably the worst part about driving a Tesla: Your car is going to testify against you. Because Tesla can and will make a statement like this, and they will always throw you under the bus. Which is a terrible way to treat a customer, as a general practice.

Presumably Tesla/the car is telling the truth as it saw it. I don't think you're suggesting they're falsifying the logs.

> Which is a terrible way to treat a customer

I'd assume that Tesla sells you a vehicle, not PR or legal services that protect you in case of an accident. Your expectation that Tesla should take the blame is unreasonable by any standard.

Re:An Update on Last Week’s Accident by ocdtrekkie on Saturday March 31, 2018 @02:13PM (#16724384)
I'm not saying Tesla is lying. But I am saying that I could spend six figures on a car from a company that is ready and waiting to stab me in the back. Or, I could spend five figures on a Toyota, knowing that Toyota is not going to sell me out if my car crashes.

I mean, look, it makes sense Tesla has to defend itself, especially legally, but there's a big difference between pulling out the logs when you need to for the lawyers and the regulators... and making a public blog post blaming the customer.

Re:An Update on Last Week’s Accident by semi-extrinsic on Saturday March 31, 2018 @05:21PM (#16725236)
I think you're absolutely correct, and moreover that the difference comes from that it's in Toyota's best interest to think about the long term, play good guy and dip into their rainy day money for any costs associated with that.

Whereas with Tesla, they're leveraged out to here with stock valuation based on promises and projections, and if their key tech is perceived as seriously flawed, they're not going to exist as a company in the long term.

Re:An Update on Last Week’s Accident by microtherion on Saturday March 31, 2018 @09:15PM (#16726130)
As far as I can tell, Toyota (or other car manufacturers) would be just as inclined to argue driver error in crashes (especially once involved in litigation). See e.g. https://users.ece.cmu.edu/~koopman/pubs/koopman14_toyota_ua_... for a discussion of some Toyota crashes.
Re:An Update on Last Week’s Accident by ocdtrekkie on Sunday April 01, 2018 @01:21AM (#16726859)
I think there's a significant difference between a company who will defend itself reasonably in court, and one which is actively collecting telemetry on your car, and will proactively write a blog about how badly you drove.
Re:An Update on Last Week’s Accident by emn13 on Saturday March 31, 2018 @05:15PM (#16725213)
There is a nuance here though: unlike a "classic" car, tesla and other modern cars clearly have access to a wealth of data about your driving and your crash. The scope of lying by omission, of even simply misinterpreting the wealth of data is much larger.

I do think it's reasonable to ask of them to either keep completely silent; or to be completely open - perhaps by giving complete access to all data to a truly independent third party, and not picking which facts they think are fit for public consumption, and which are not.

I admire what Tesla has achieved - but this is a company under considerable pressure. They may well go bankrupt; and every incident matters. They are under terrible pressure to massage those facts to make them look good. I can't help but treat any statement like this no differently to any other ad - it's easily possible to be misleading even when there is some possible interpretation that isn't an intentional untruth.

Everybody knows people aren't good at sitting around doing nothing and maintaining focus. Distracted driving isn't a new risk. So the question is: are the safety benefits to a driver aid really greater than the risk they cause by encouraging distraction? Even if the driver aid catches 99% of all risks, that may yet be a net negative. Personally, I don't think it's reasonable for a system that encourages distracted driving to then claim it was the driver's fault they were distracted. No amount of small print or big fat warnings can ever excuse ignoring reality. If the autopilot is contributing to driver inattention, then the driver's inattention is no longer just the driver's fault. Not that I'm at all sure that's what's happening here, but there are some ominous indications, that is for sure. Without an autopilot, who takes their hands off the wheel for more than 6 seconds on a drive like that?

You know how many plane crashes are not the fault of human error? Very few.

I have a friend that investigates planet crashes. He’s told me that between pilot error, human error, hubris, flying when conditions are too dangerous, poorly trained or sloppy mechanics only about about 1% really can’t be classified as being caused by humans. He said the stats are a bit skewed because like any organization that reports on human performance they’ve been influenced to be a bit “flexible” when assigning blame.

Re:An Update on Last Week’s Accident by NelsonMinar on Saturday March 31, 2018 @10:58AM (#16723550)
Some of this is a quirk of how the NTSB reports accidents. For instance if a small plane suffers engine loss in flight, the cause of the accident will be listed as "failure of pilot to land the aircraft safely without power". Which is technically true, but most ordinary folks would blame the engine failure for the crash, not the pilot. It reflects a culture where the pilot is absolutely responsible for the aircraft and its passengers. That's the exact opposite of where the self-driving car industry is going.
Re:An Update on Last Week’s Accident by andrewprock on Saturday March 31, 2018 @07:44PM (#16725792)
Human error is distinct from driver/pilot error. It's possible (though quite unlikely) that there 0% pilot error in all plane crashes, and 99% human error.

Given that plane auotpilots are roughly comparable with Tesla's autopilots, one wonders how many plane crashes have occurred while the plane was in autopilot, and what fraction of those crashes were attributed to pilot error.

Sadly I have to agree with you on the narrative angle. While I am very impressed with what Tesla has accomplished in their autopilot I find the careful construction and omissions in this follow up post to be done poorly.

They omit what speed and what lane the car was travelling in. They omit the time at which the car was no longer behaving in the way in which it had (when did it start heading for the crash barrier? At what point did the wheels closest to the barrier move over the line? etc)

They have previously mentioned that their cars have navigated this spot many times in the past (over 200 as I recall) did they note the number with and without the crash barrier intact? How many times was the car in the exit lane and how many times in the lane to the right of the exit lane? How many times have they navigated past it with a damaged crash barrier.

The driver had driven this route before, it was his commute to work. Had he driven it with this car on that route in autopilot before? Did it work then? How many times? How many seconds were there between when the driver's car was doing something right (in lane etc) and doing something wrong (straddling the lane). The response indicates there were 5 seconds of visibility coming up to the crash barrier, at what point was the autopilot on a collision course? All of those five seconds? or the last 500mS ?

Reading the Tesla response I felt I wasn't getting the whole story, and was getting a whole lot of deflection. That isn't the tone that inspires confidence in me. And that makes me sad because they have done much better in the past. I cannot help but speculate that this time they feel they might have been contributory at least and that a full disclosure would be used against them in a civil suit.

Re:An Update on Last Week’s Accident by Rapzid on Saturday March 31, 2018 @04:30AM (#16722373)
Yeah, it's pretty crafty PR. The CPC must be green with envy, while Uber is still ruing their reputation. Such a difference in conversation; so many people laying the blame squarely on the driver(he is ultimately the PIC tbh, but Tesla and particularly CalTrans messed up bad), however Uber is being raked through the coals when somebody literally walked in front of their car..

Just Say'n

EDIT: While I believe Tesla and the driver are the ultimate source of the accident, I believe CalTrans messed up worse with that barrier. At least Tesla owns up to the limitations and warns drivers to stay in control, but why the hell was that barrier not replace d?! What systemic mediocracy is playing out there that they have road work signs with dates 3 years old on them, and a critical safety barrier is just missing with traffic flow as usual?!

Re:An Update on Last Week’s Accident by pja on Saturday March 31, 2018 @05:08AM (#16722470)
somebody literally walked in front of their car..

The analysis I've seen suggested that the self-driving system in the Uber vehicle had 4 or 5 seconds to detect the pedestrian crossing the road in front of them. Driving into a pedestrian on the road in that circumstance is /not/ acceptable for any driver, be they human or automated.

Don't be fooled by the video footage Uber released from the in-car camera - the quality is appalling. Compare it with the dashcam footage taken by people driving the same road at the same time & you'll see that visibility should have been perfect & a human driver would easily have avoided the pedestrian who was doing something that all of do every day - crossing the road.

Re:An Update on Last Week’s Accident by Rapzid on Saturday March 31, 2018 @05:19AM (#16722513)
It is acceptable though, most people wouldn't even get involuntary manslaughter which still requires criminal negligence. People are really spouting off here and project in their own superiority onto the situation. It's a situation similar to when a child gets left in a car or jumps a zoo fence, "I never take my eye off my kids even for one second even when I'm sleeping. I would never allow that to happen to my kids. Worst parent/person who has ever walked the earth".

Not only did the pedestrian instigate that, the failsafe(which are supposed to be very simple to back up complex and more fallable systems) to not getting hit and killed by a car was entirely in the pedestrians area of responsibility; don't walk into traffic.

Re:An Update on Last Week’s Accident by usernam on Saturday March 31, 2018 @08:43AM (#16723052)
At least here, the driver of the vehicle hitting anything (another car, especially a person) is /always/ responsible, because you're supposed to be attentive for unexpected events. And that's how it should be. Why do you think otherwise? If you don't see clearly in front of you because of scarce illumination, you should go slower.

Unless assisted driving is close to near perfection (that is, it becomes a true auto-pilot without the need of assistance), we're going to see much worse numbers of accidents on the streets for assisted-driving cars.

Assisted-driving requires the same, if not more attention, as it essentially becomes like supervising an inexperienced driver that is prone to make stupid mistakes in otherwise normal circumstances. If you ever had a kid, you should be pretty familiar with how stressful this is.

But thanks to the PR spin, the driver is led to think that he can keep less attention, until he pays none at all. Assisted driving is even more boring than regular driving, lowering the attention span.

What could possibly go wrong?

Re:An Update on Last Week’s Accident by pja on Saturday March 31, 2018 @05:44AM (#16722582)
I disagree with your implied belief that cars should have priority on the roads & that in every collision with a pedestrian it's implicitly the pedestrian who is at fault unless it can be proven otherwise.

We all owe each other a duty of care. Excuses about 'she just walked out in front of me' are just that: excuses. The driver in this case had plenty of time to slow down and avoid a collision & simply chose not to do so. That's inexcusable.

The fact that the driver was a pile of self-driving code doesn't change that one iota.

No. Children wander into roads. Drivers have a responsibility to keep an eye out for the unexpected. They are faultless only if they were driving responsibly and had no opportunity to react — neither of which were the case with the Uber.

I think CalTrans owed up to its limitations: you should expect the road to be flat and not end abruptly without appropriate signage. But you are fully responsible to control the vehicle at all times and maintain an appropriate speed - so that when the road does inevitably end you can react safely. At no point are the crash atenuators a guaranteed component that the user of the road can expect to be in place and should rely on to save his life.

That is not to say CalTrans did not break some contractual obligations to replace that infrastructure in a reasonable timeframe, and shouldn't be held responsible in a commercial sense. But they are not in any way liable for the accident, the missing hardware was not a reason to stop traffic and all such devices are offered on a best effort, good to have, basis.

It's widely known that RADAR systems are not able to detect stationary objects, only moving ones. Actually, they are are to detect them but just not where they come from, so a barrier in the middle of the road and a traffic sign on the side of the street, they would look like the same to the RADAR system.

But to be honest, I am more worried with the markings of the road rather than the inability of the autopilot of not foreseeing the accident: https://imgur.com/a/hAeQI

What's wrong with the US road administration? Why is this even look like a driving line? Where are the obvious markings? It's a very misleading road layout, I am curious the amount of accidents that happen there every year.

This is how I expect this kind of thing to look like: https://i.imgur.com/dfZehmd.gif

Given on how the road looks like, it makes more sense why Tesla is reinforcing the fact that the driver wasn't paying attention to the road.

Edit: Since people are curious about the limitations of the RADAR, the manual of the car mentions this limitation:

"Traffic-Aware Cruise Control cannot detect all objects and may not brake/decelerate for stationary vehicles, especially in situations when you are driving over 50 mph (80 km/h) and a vehicle you are following moves out of your driving path and a stationary vehicle or object is in front of you instead."

That doesn't make any sense. Radar systems do detect stationary objects just fine. In fact, from the point of view of the moving car, almost nothing is stationary.

I wouldn't be surprised if you're correct about the markings on the road, I almost crashed into a temporary barrier driving at night, because there were two sets of lane markings - the old ones, and the ones going around the barrier. Construction workers simply didn't bother to erase the old ones.

Re:An Update on Last Week’s Accident by saalweachter on Saturday March 31, 2018 @07:36AM (#16722853)
This is not a RADAR problem, it’s a world modeling problem.

So you’re sending out pulses and listening for echos, which tells you how far away something is in a particular direction. You correlate subsequent pulses to say whether the object is moving toward you or away. If you have a car 50 m ahead of you every time you ping, everything is good. Now that car suddenly swerves around a car stopped in front of it, and your ping off that object says 60 m. A crash is less likely, your model thinks! The object in front of you is rapidly speeding away! By the time it realizes it isn’t, boom, crash.

Re:An Update on Last Week’s Accident by adamlett on Saturday March 31, 2018 @08:03AM (#16722934)
That’s not how it works in my limited understanding. Radars don’t just detect the positions of object, but also their relative speed. For this, they take advantage of the Doppler effect. When a pulse gets reflected, its frequency rises if the object is moving towards the radar, and falls if it’s moving away.
Re:An Update on Last Week’s Accident by saalweachter on Saturday March 31, 2018 @08:18AM (#16722978)
You could be right, either in this case or other cases. I'm entirely inferring what autos are doing based on their failure case (not detecting stationary cars when the car in front of you swerves around them); that sounds a helluva lot like mistaking the new car for the old.

Again, not saying it's a limitation of RADAR; it sounds like a deficiency in the way they're using it.

Re:An Update on Last Week’s Accident by hexane360 on Saturday March 31, 2018 @07:54PM (#16725824)
Although there's an inherent trade-off between detecting position and speed. Longer pulses give more accurate frequency/speed detection, while short pulses give more accurate time/position detection. This is the same phenomenon that underlies Heisenberg uncertainty.
Re:An Update on Last Week’s Accident by gus_massa on Saturday March 31, 2018 @07:35AM (#16722851)
IIRC the radar can detect the object but it has too many false positives, like a small soda can that has a lucky alienation and shape that make it appear as a big object. So the system ignores the static signals of the radar, because randomly stopping each time an small object is confused with a big object is also dangerous. And the system uses other signals to identify and avoid static objects.

What the fuck? That's not at all how radar works. It has no such limitation.

Re:An Update on Last Week’s Accident by pja on Saturday March 31, 2018 @07:46AM (#16722888)
My understanding is that RADAR systems can detect stationary objects just fine: What's going on is that in-car radar systems can't differentiate between, say, a metal sign on a gantry or at the side of the road and a parked car on the road, because their spatial resolution is poor to non-existent. Hence in-car RADAR systems (often) ignore radar returns that are non-moving relative to the road surface. Otherwise the car would panic brake every time you went past a road sign.

The effect of this is that current in car RADAR systems are great at avoiding collisions with vehicles that suddenly brake to a halt in front of you whilst at the same time will happily let you drive a full speed straight into the back of a parked car.

This is why I believe current self driving vehicles (apart from Tesla) are all using LIDAR for object detection.

(The above is my interpretation of my reading on the current state of the art. If anyone knows more detail, please correct me.)

Re:An Update on Last Week’s Accident by URSpider94 on Saturday March 31, 2018 @03:18PM (#16724683)
The problem for all self-driving car systems is modeling the road. Let’s say you are climbing a gentle hill, and there’s an overpass ahead. The nose of the car is aiming up, so it will see the overpass dead ahead and not moving. This looks the same to the car as driving down a flat road with a semi perpendicular to the travel lanes and dead stopped. This is true for all imaging systems - RADAR, LIDAR and camera.

Same if you are about to enter a right-hand sweeper, pedestrians standing on the sidewalk in front of you would look as if they are directly in your path.

Musk mentioned this in one of his blog posts. Tesla is attempting to build a database of obstacles like this and geotag them, so that the car can filter them out.

Uh, what?

I think you're thinking of Doppler radar systems. You can do static scene imaging with radar, no problems (I've written the code to do it, even!).

There's no way in hell a car is going to be using a Doppler radar. In all likelyhood, they're using a plain-old FMCW system, and it can absolutely detect stationary stuff.

While I find it deplorable that several companies are essentially using people, although in this case apparently willing, participants in testing auto pilot or autonomous driving software. I also find the lack of prominent road markings, signage, or any significant shock absorbing zone simply astonishing!

It makes me wonder, is that layout actually on purpose? I truly find it hard to believe that a road or traffic authority in this day and age could design that on purpose! It's quite well known that human attention is a tenous thing, and that the attention given to an object is primarily proportional to its size. But here we have a barrier end that is signed as being about as dangerous as a a bit of debris.

Re:An Update on Last Week’s Accident by ineedasername on Saturday March 31, 2018 @05:00PM (#16725150)
autopilots do a bit more than maintain course, they can basically execute the entire flight-plan in between takeoff & landing, which includes plenty of heading adjustments. They also increasingly do a fair bit of heavy lifting on landings as well.
Re:An Update on Last Week’s Accident by emn13 on Saturday March 31, 2018 @05:27PM (#16725257)
A plane is much easier to navigate because there aren't things like lane-dividers floating about. That's handy, but alas it does not apply to driving a car.

Just because an in-air navigation aid that allows for essentially pilot-free navigation deserving of the name "autopilot" happens to be relatively trivial to build, does not mean any navigation aid of similar complexity for other modes of transport should be called autopilot simply because they're at least as complex. If you're not automatically piloting, the name autopilot is pretty disingenuous, is it not?

Also, planes have a bunch of other navigation aids, including collision avoidance systems and ground-based air traffic control, and pretty obvious stuff like predictable flight paths and huge safety margins between nearby aircraft. An autopilot for an airplane works in that context. I kind of doubt it would work if there were thousands of planes nearby, many of which are on paths separated by distances the vehicles in question cover in tiny fractions of a second, and some of which follow almost invisible rather unpredictable paths (that drunk guy without lights over there...). Context matters.

Re:An Update on Last Week’s Accident by ineedasername on Saturday March 31, 2018 @10:33PM (#16726386)
I think what I'm taking issue with isn't anything about comparing them to self driving cars, it's that you characterize them as "trivial to build". They are not. They coordinate a significant number of life-critical systems, react to minute perturbations in the air stream with microsecond precision, and do so with such a high level of precision that human pilots are often forbidden from overriding them outside of specific situations. I don't know what gave you the impression that these systems were basic or trivial, but they have been at the cutting edge of systems automation for decades.
Re:An Update on Last Week’s Accident by emn13 on Sunday April 01, 2018 @02:08AM (#16727002)
Compared to a self-driving car system, they are trivial. Your assertion that "they have been at the cutting edge of systems automation for decades" kind of indicates that - this stuff is simple enough to make that it was feasible to do even that long ago.

Trivial is good mind you because it actually works, and works reliably. The same is not yet clear of self-driving cars.

If we are moving towards a future with self driving cars there needs standardization of road markers so that cars can recognize what's going on.

This crash is looking to be the autopilots due to the strange lane markings.

Have you ever driven down a road the lines grinded away and replace by new ones? Sometimes you can still see both sets, it can be pretty confusing for a human.

Radars do just fine detecting stationary objects, what they can't do is tell whether the stationary object is blocking the road, overhead, or to the side of a curve in the road. As most radar reports of stationary objects fall in the latter two categories, the adaptive cruise control system filters them out of consideration.

Yeah, there is so much wrong going on with that road. The divider warning sign is also lower than a standard car.

They're marked 'optional' on your diagram. Optional things can be excluded.
Re:An Update on Last Week’s Accident by jstanley on Saturday March 31, 2018 @09:47AM (#16723268)
"Optional" doesn't mean "exclude it if you feel like it". It means "think about it and decide whether it's worth adding". They can be excluded if doing so doesn't present a danger (e.g. it's a small road).

From the one photograph we've seen of the slip road in question, I'd say the lack of chevrons poses quite a serious danger. It looks just like a normal lane. I've never noticed a slip road branch off like that in the UK, i.e. a big crash barrier up the middle but no chevrons.

(I'm not saying whoever designed this section of road is guilty of some sort of crime, or is somehow responsible for the crashes, I'm just saying it should have been designed better).

And look who fell for it (techcrunch):

"However, it seems the driver ignored the vehicle’s warnings to take back control" [1]

Followed by the quote from Tesla that at some point in the history of the ride a warning of some sort was given.

>> The driver had received several visual and one audible hands-on warning earlier in the drive

> What they are saying is that while he was driving there was an earlier point at which the car did not crash, where the car gave a visual and audible clues. And you have to ask? Why the hell is that relevant?

I see it being relevant that the driver had his follow distance set to the lowest and that several times in the drive prior to the accident he had to be prompted to maintain his hands on the wheel. This speaks to a driver that wasn't paying attention like they were supposed to be doing. That would increase the likelihood of him missing an upcoming hazard and responding in time.

Regardless of that, if he had reported and issue in that area to Tesla, why the hell was he not driving it himself at the time? I know that I personally value my life enough that I wouldn't trust AP if it had been veering into the wall repeatedly in one area.

Yes. But as we all know autopilot is not the same as self-driving.

>> And no, you can't get out of culpability by claiming statistical superiority.

In fact no one has found Tesla culpable for the accident. You can however defend the safety of your system by referring to statistics. (In fact that is the ONLY way to measure safety level) And your analogy does not hold. It it more like a parachute company saying their parachutes are safer than other brands because it fails less often than the other brands. Which brings me to my final point. Even if it turns out Tesla was culpable and negligent in this accident, it would not be a complete judgment if we leave out the inherent risks in car manufacturing and the incidents attributed to other companies.

Re:An Update on Last Week’s Accident by danso on Saturday March 31, 2018 @04:01PM (#16724896)
I'm pretty sympathetic with PR departments doing what they have to do, in terms of putting out the official boilerplate remorse, the promises to cooperate and keep people up to date, as well as publishing the incident data, and then keeping mum until the investigation is finished.

But Tesla is shoveling in the bullshit pretty early on. Besides the fuzzy and deliberately vague stats (why is the mileage attributed to Tesla's "equipped with Autopilot hardware"?), this graf is just despicable:

> Tesla Autopilot does not prevent all accidents – such a standard would be impossible – but it makes them much less likely to occur. It unequivocally makes the world safer for the vehicle occupants, pedestrians and cyclists.

"unequivocally" has an actual meaning: leaving no doubt. And yet it's used following the paragraph that pretends Tesla's and all U.S. vehicles are directly comparable. I know it sounds silly to focus on that word but someone in Tesla PR thought it needed to be used with the pile of crap numbers. Such blatant and pointless deception -- "significantly" would work just as well for that inane sentence -- feels like a strong a signal to doubt the rest of the info given, as if the evidence weren't already so obviously dubious.

Vehicle notifies the driver it's having difficulty operating the driver elected auto pilot mode based on the conditions. Driver elects to continue using the failing operating mode despite being warned.

I fail to understand how "It isn't" relevant that the driver chose not to take manual control when warned that conditions were not ideal.

Perhaps they don't know (yet?) what exactly went wrong? The car was heavily destroyed, I am surprised they got any logs retrieved from the car at all. They might be able to reconstruct more information about the accident, but unless they have a complete log including video (unlikely), it will take time to reconstruct. As there is an ongoing investigation about the accident, it is understandable, that they are not making any statements beyond anything they can prove without a doubt at the current point of time.
Re:An Update on Last Week’s Accident by Rapzid on Saturday March 31, 2018 @04:49AM (#16722423)
Sure, but the ONLY reason many of us can figure for mentioning the previous warnings in the way they did is because the way it would.get interpreted as a sound bite. Could be wrong, but this isn't conspiracy theory territory. These companies have teams of highly paid communications experts(spinsters) engaging in social engineering.

Like you’ve predicted, first headline on Techmeme: “Tesla says Autopilot was engaged during fatal Model X crash on Mar. 23, and the driver didn’t respond to warnings to take control of the car before the crash”. Although the linked article has a different title; might’ve been changed.

Also, ever notice how in none of the Tesla Autopilot accidents, Tesla finds itself guilty?

I don't even read these posts from Tesla anymore because I know each one of them is just justification for how Tesla did nothing wrong, and it's the fault of the stupid human driver for using its Autopilot "wrong" and dying in the process. Meanwhile, Tesla is laughing all the way to the bank selling the usage of Autopilot as one of the primary features of its cars.

It almost reminds me of how Coke markets its sugar-filled soda "Drink as much as you can at every meal and at any event...but you know, in moderation (because that's what the government makes us say with its dietary guidelines)".

Tesla is kind of like that. It tells people to use Autopilot because it's such a great experience and whatnot, but then stuffs its terms and conditions with stuff like "but don't you dare to actually lay back and enjoy the Autopilot driving. You need to watch the car like a hawk, and if you happen to ignore any of our warnings, well it's your stupid-ass fault for ignoring them, even though we wrote everything there in the 11-point font." It's very irresponsible for any company to do stuff like this.

I don't know what the exact process is now, but I wish the authorities would be able to get access to un-tampered logs of the accident after the fact from the self-driving car companies.

I don't care if it's a car company that has "Elon Musk's reputation" (who I like) or Uber's reputation. These accidents, especially the deadly ones, should be investigated thoroughly. No company will ever have the incentive to show proof that leads to itself becoming guilty. It's the job of the authorities to independently (and hopefully impartially) verify those facts.

I'm a big fan of Tesla and its electric vehicles, big fan of Tesla Energy, big fan of SpaceX. But I've always criticized them for the Autopilot because it was obvious to me from day one that they're being very irresponsible with it and putting the blame on humans, when they were marketing it as a self-driving feature (they did for years, even if they don't do it as much now, but they still use the same name), while its system is far from being anywhere close to a complete self-driving system, and thus putting anyone who uses in danger of dying.

Re:An Update on Last Week’s Accident by Amezarak on Saturday March 31, 2018 @09:39AM (#16723240)
Tesla's huge success in people's mindspace of self-driving vehicles is baffling to me. Correct me if I'm wrong, but these are the self-driving features in Teslas:

- Cruise control maintains speed, will automatically decelerate if a car in front slows down, speed back up if they speed or go away, etc.

- Collision avoidance: the car will automatically emergency brake if it believes a collision is imminent.

- Lanekeeping: the car will stay in the lane without driver attention, although if it doesn't detect your hands on the wheel with enough frequency, the system will disengage.

- The car can park itself.

A quick look at Wikipedia tells me it can also change lanes and be "summoned."

Most of these features, especially considering cruise control, collision avoidance, and lane-keeping as the core featureset, since at least in 2017, have been in wide deployment among most car manufacturers, down to even cheap economy cars, that people are buying right now without getting on waiting lists or anything of the kind. You can buy a car right now with this core featureset for around ~18k.

Not only that, people seem to dramatically overestimate what kind of auto-pilot Teslas have. Speaking with my doctor about it, he assured me that "you just tell the car where to go, and it goes there." How did Teslas get so hyped up in the common man's imagination?

Re:An Update on Last Week’s Accident by zmarty on Saturday March 31, 2018 @06:52PM (#16725591)
Yeah, I'm going to call BS on this one. More specifically, on the lanekeeping claim. The current non-Tesla implementations are worse or much more limited at the price point you mentioned (and frankly, at most price points).
Re:An Update on Last Week’s Accident by Amezarak on Saturday March 31, 2018 @06:58PM (#16725617)
All I can tell you is that the Honda lanekeeping does everything I would expect or want, and its the only one I have a lot of experience with. The only thing that annoys me is that it requires you touch the wheel every now and then.

Can you elucidate on what tesla lanekeeping does that others don't?

> It's very irresponsible for any company to do stuff like this.

It's very irresponsible for regulation to allow them to do that. And statistically for us to vote for politics that are not against that kind of behavior. Big companies rarely give a shit about killing people in the process of making money, as long as they are not punished for doing that. (And we, btw, mostly don't give a shit when the people being killed live in other countries, even when the process to do so is far more direct than the 1st world problem that interest us here.) People who used to organize those kind of criminal behaviors used to be held responsible for the consequences, but it is more rare now and the laws in various countries have actually been changed so that people managing companies are far less accountable than before for the illegal and otherwise bad things they order. As for companies being accountable, it is usually in punitive money that is order of magnitude less amount than the extra profit they made in doing their shit, so why would them stop? The risk of the CEO being sent to jail would stop them. Ridiculously small fines against the company, in the astonishingly rare cases where they even actually fined, not so.

Re:An Update on Last Week’s Accident by snarfy on Saturday March 31, 2018 @08:30AM (#16723016)
