Humans have a tolerance for human-style accidents, but not robotic-style accidents. A dipshit that pulls in front of you to t-bone is a human-style accident that is acceptable. A tesla that sees a river and thinks it's a road is a robotic-style accident. It's going to take centuries for us to become acclimated to how machines mess things up.

Is it unreasonable?

One can learn to drive defensively, and be able to spot the said dipshit in advance, decreasing the likelihood of collision.

Yes, not in all cases, but there's a bell curve. As humans, we can read other humans.

Robots aren't inherently bad either. I love my Roomba precisely because if it fails, it fails predictably. I can and do make my apartment Roomba-friendly.

But the self-driving deep learning-driven cars don't have this feature. They fail unpredictabily, as in your example. We don't have an understanding of what really drives the decision-making there. And we keep discovering failure modes as they manifest.

One day, the car might think the river is a road. Another, it will not recognize a road block as such. But only if it's a Tuesday. Or something. We really don't know.

So I don't think we'll get acclimated to that. Unpredictable failure is a reasonable thing to be afraid of.

I'd argue it is unreasonable given that (afaik) no one is marketing a self-driving car that doesn't also require a driver be attentive at all times.

You can learn to drive a self-driving car defensively, in the same way you learn to drive a normal car defensively. Pay attention to your surroundings, blind spots, and other cars.

Maybe self-driving is a poor term to use.

>You can learn to drive a self-driving car defensively

My point was that you can't learn to drive a normal car defensively if there are self-driving cars on the road (in their current form).

When a self-driving car decides to do something stupid, you won't see it coming because the decision tree is literally beyond human comprehension.

See: http://www.bbc.com/future/story/20181204-why-we-should-worry...

And Uber's and Tesla's accidents have shown us that you can't rely on the human in the car to catch it before it does something stupid. After all, teaching someone how to drive and watching them attentively is difficult work.

Tesla's marketing videos for Autopilot have a caption along the lines of "driver is only present for legal reasons".

Then it is not a self driving car, maybe let's named them human supervised self running cars

Re:Ford CEO says the company 'overestimated' self-driving cars by cblades on Thursday April 11, 2019 @01:56PM (#19637319)
Exactly, that was my point.

There are no self-driving cars on the market, or in development by major car manufacturers.

They all explicitly require human attention.

Re:Ford CEO says the company 'overestimated' self-driving cars by fwip on Thursday April 11, 2019 @02:38PM (#19637766)
It's especially bad because us humans supervising the cars are going to be worried about preventing human-style accidents. Maybe you're worried about it following too close or not noticing the red light - so you don't notice the warning signs in time when it veers into the concrete barrier.

Humans fail in unpredictable ways all the time. Look at the cases of people using vehicles as a weapon of terrorism. How are we supposed to predict that?

Yeah, we can go back and investigate the person's life and say "see, they had a history of browsing extremist websites, making bigoted comments, suicidal thoughts, etc." The problem is that this description fits a very large group of people, compared to the subgroup which actually carry out the attacks.

So while it is true that we may have difficulty (or it may even be impossible) auditing a self driving car after the fact, it should not be any more comforting to know that human failure can be explained after the fact, given that the human failure was not predicted beforehand.

You can get 99% of the way there with extremely detailed maps. Where the road is, where the lanes are, what the speed limit is, where to find stoplights and rail signals, where to be extra-cautious, how to navigate through a construction zone, all can be pre-programmed.

A Waymo is basically just following a virtual track on an extremely detailed LIDAR map of the area, obsessively watching for pedestrians and following the rules of the road the best it can. It will never think a river is a road.

Not to say that there aren't a million little things to be concerned about with this approach, or that there aren't major things to overcome (like heavy snow on the ground making your LIDAR map useless). But I think we'll get there, and in many places soon. There's nothing that says this tech has to exist everywhere out the gate.

Re:Ford CEO says the company 'overestimated' self-driving cars by foobiekr on Thursday April 11, 2019 @01:52PM (#19637271)
Tesla's approach thinks white trailers are open sky. The river comparison is not unreasonable at all.

Almost all of the startups in the space are following the Tesla approach of just throwing machine learning at the problem which means almost all work in the space suffers from novel input producing unpredictable results. This is one of the things that has killed trained and evolved systems in the past and the fact that few of the companies in this space are even trying to manage it (either by building interpretable models or by using models and using ML to do parameter fitting) is a good indicator that the whole business is either a fraud or is built on the premise that with enough data or, for the un-cautious and unaware, enough simulation, the problem solves itself.

I think what we are actually seeing is that Waymo (where, in ten years, they might have a solution) and Tesla (which is mostly worst-in-class but as a company is the master of hype) drove hype around self-driving. Then Uber and Lyft latched on (because they needed a story to paper over their terrible economics) and pushed it even higher. The Otto thing and Cruise's acquisition made VCs pay attention.

So these companies are acquisition bait for the assumed-clueless big auto companies. They will not deliver self-driving cars. At best they will deliver next-generation enhancements to emergency braking, etc.

A Tesla is not a self-driving car. Autopilot is an assistive technology.

They can change the construction zones on any given day - adjust the lane changes, move the barriers a foot over, or add a new fence where there wasn't one yesterday.

You would think then a cooperative system between human and robot would be therefore be the best option. The human prevents the robot from driving into a river and the robot prevents the human from t-boning someone else. Except most people on HN seem to be completely against this type of cooperative system and would only support self driving tech when it gets to level 4 or even level 5 autonomy.
Re:Ford CEO says the company 'overestimated' self-driving cars by wvenable on Thursday April 11, 2019 @01:29PM (#19636988)
I'm not sure how such a system could possibly work; human attention doesn't work that way. If the robot drive 2 hours and 35 minutes just fine and one minute later decides to drive off the road, how is a human going to react to that? It's not really possible.

If a human has to pay attention all the time, then they might as well just be driving.

And one of the advantages of self driving cars will be freedom for the elderly and disabled who already have difficulty driving cars. This is the group, in my opinion, that will benefit the most from self driving cars.

Right now the self driving tech doesn't do anything to communicate with the driver besides just a general warning. However that doesn't have to be the case. Maybe some type of confidence indicator should be added. A simple green, yellow, red warning system could help a driver know when a self driving car might not be as certain in its surroundings.

>If a human has to pay attention all the time, then they might as well just be driving.

I just don't get this mindset. There are different levels of "paying attention" that require different levels of mental energy. The discussion also isn't made with nearly any other driver assist technology. No one suggests that automatic transmissions or cruise control are worthless because the driver still has to pay attention.

>And one of the advantages of self driving cars will be freedom for the elderly and disabled who already have difficulty driving cars. This is the group, in my opinion, that will benefit the most from self driving cars.

I agree with that, but it doesn't mean that other drivers won't benefit as well.

I think this probably fails to understand how quickly it's making decisions, how quickly the situation could change, or how it could even judge it's own confidence. It could quite confidently drive you into a river; it's not likely to do that unless it's pretty sure it's a road.

As self-driving technology gets better, the robot is going to be much better and the failure situations much more rare.

> I just don't get this mindset. There are different levels of "paying attention" that require different levels of mental energy.

If one doesn't have to provide direction or speed, there is literally nothing to keep a human attentive enough to make a difference. You expect someone to passively look at a green/red/yellow indicator for hours at a time while not otherwise engaged with driving? And then when that indicator turns red you expect them to immediately be able to make a useful judgement? I think humans are more than likely to make that situation worse!

> The discussion also isn't made with nearly any other driver assist technology. No one suggests that automatic transmissions or cruise control are worthless because the driver still has to pay attention.

There is a huge difference. If you have cruise control or automatic transmission, the vehicle still doesn't go where it's supposed to without you paying attention. The driver still has to pay attention because they have to pay attention or they don't anywhere. With self driving cars, the driver is now a passenger and doesn't have to pay attention for the vehicle to work.

Re:Ford CEO says the company 'overestimated' self-driving cars by slg on Thursday April 11, 2019 @02:47PM (#19637869)
I haven't seen any evidence of a self driving car accident in which the car had no potential to warn the driver. All the examples I have seen are when a car misidentifies on object in its path as a non-threat. The problem is that breaking and/or swerving are very drastic actions. There is therefore a deservedly high barrier before a system is willing to take those actions. At the worst you could have two systems running in parallel and one is tuned to be much more aggressive in making those decisions and that information is communicated to the driver.

No self driving car that doesn't have at least level 4 autonomy allows the driver to not pay attention like you are suggesting. The benefit of a cooperative tech is that it takes mental load off the driver. Like I said previously, there are different levels of mental energy that a person can spend on a task. It isn't like the choices are either 100% or 0% of your attention.

Re:Ford CEO says the company 'overestimated' self-driving cars by nradov on Friday April 12, 2019 @12:38PM (#19646410)
Such systems work fine. The human does have to be constantly driving, but the computer intervenes when it detects the human doing something dangerous. Look at automated GCAS in aircraft.
Re:Ford CEO says the company 'overestimated' self-driving cars by wvenable on Friday April 12, 2019 @02:24PM (#19647601)
That's not self-driving though. There are plenty of driver-assist technologies (automatic breaking, for example) but that's not the subject at hand.
Re:Ford CEO says the company 'overestimated' self-driving cars by nradov on Friday April 12, 2019 @02:56PM (#19647902)
Full self driving in the general case will probably not exist in our lifetimes. It's like chasing an imaginary pot of gold at the end of a rainbow. So the industry should aim for goals that are actually technically feasible and will deliver tangible safety improvements.
Re:Ford CEO says the company 'overestimated' self-driving cars by wvenable on Friday April 12, 2019 @04:30PM (#19648669)
I disagree. The progress of camera and laser technology, in addition to AI, is improving at an incredible rate. The market for self-driving vehicles is huge -- any company that figures it out will make billions (maybe trillions).

Computers can have a perfect 360 degree view and track and categorize every object around them. Humans will be both physically and intellectually outmatched eventually. And humans just aren't that good at driving on average.

Re:Ford CEO says the company 'overestimated' self-driving cars by nradov on Friday April 12, 2019 @07:02PM (#19649810)
You're welcome to disagree, but so far there's no hard evidence to support your viewpoint. Just a lot of hype.

Past rates of progress are not indicative of the future. The easy problems have already been solved. Now progress is already slowing down.

In particular the notion that computer vision can reliably track and categorize every object is just laughable. The state of computer vision research is nowhere close to that capability. Errors are frequent, especially under adverse conditions.

In November 2017, Waymo announced that it had begun testing driverless cars without a safety driver in the driver position. In October 2018, Waymo announced that its test vehicles had traveled in automated mode for over 10,000,000 miles (16,000,000 km), increasing by about 1,000,000 miles (1,600,000 kilometres) per month.

In Arizona, Waymo has fully autonomous taxi service you can use right now. https://waymo.com/apply/

Is that a lot of hype? Maybe.

> Humans have a tolerance for human-style accidents, but not robotic-style accidents.

I think it's more because there's someone to yell at - someone to blame.

Think of it like a taxi driver with a passenger; people ride in these all the time, or uber, or lyft - and have no problems doing so. Even though they aren't in control, and they have no idea about the driver's driving capability. They assume the driver is an average to better driver, when that may not be the case at all. So what happens when an accident occurs?

Well - if the passenger is still alive, and believes it to be their driver's fault, they can yell at their driver. If they believe it's the other driver's fault, they can yell at them...and so forth.

But you put a robot in place of any driver - then who can you yell at when an accident occurs? Nobody. You can yell all you want, you can even blame the corporation that made the car/robot - but you are still yelling at a machine. It won't change anything. It won't feel bad. It probably won't even make you feel better, because it won't restore your agency in the situation.

That's my guess anyhow - pulled straight from my nether regions, with nothing to back it up. I wonder if there have been any studies on this? Are there any data on what happens in other "self-driving" incidents; like perhaps completely automated trains with no humans other than passengers on-board? Do such things even exist?

Or do companies already know this - and put a human "in charge" to take the blame and heat for when an accident happens (maybe they also provide an e-stop button for the human to press - whether it's actually connected to anything or not - but it's logged as to whether it was pressed, just to help "assign blame" later)...?

While I have no proof or anything to back this assertion or theory up, it seems like it would match human nature. When things go wrong, humans want to blame somebody - some actual, sentient being. I'm sure there's a psychological term for this need and the action; I don't know what that term is, but I'm almost certain it's been studied.

Essentially one of two things would have to be done to overcome this: Either the machine would have to become perfect at driving and avoiding accidents (even to the point of avoiding things of natural random consequence, such as rocks falling on the road, or something of that nature) - or it will have to become more sentient, and ideally emotive; that is a GAI with human traits.

The former is likely impossible - randomness will always get ya; even trains have what should be "avoidable" accidents.

The latter - well, if it's achievable; that is, if we can make such a GAI, etc - it will likely also suffer the same problems humans do, most notably that we are failable and we make mistakes.

...but at least then we can blame them on something, right?

Re:Ford CEO says the company 'overestimated' self-driving cars by afiori on Friday April 12, 2019 @07:26AM (#19643811)
We all accept risk in our lives, in most cases the qualitative characteristics of the risk are the more important one. I don't really have a good enough answer to your point, but I find it morally unsettling that many people would agree with this.

One example I can think of is Russian Roulette. I would be quite a different game if each player had to shoot the neighbour instead of himself. It would be literally the same expected outcome, but an entirely different game.

Each human I encounter everyday has a small chance of murdering me (let say one in a million) would I like a robot wandering around with one in a billion chance of murdering others?

We accept that we cannot endlessly manipulate and control other humans, that we cannot forcibly "fix" arseholes, we have no such limitations for robots.

We already have an example of strong automation-driven transports: aeroplanes. Honestly I see no reason to have lower standards for self-driving cars.

>When things go wrong, humans want to blame somebody - some actual, sentient being.

Exactly! When (not if) a fully autonomous self-driving car causes a terrible accident resulting in death, how are the loved ones going to feel when they've only got a company to blame? In such an emotional situation, the response needs to be better than Uber or whoever saying "we're very sorry our car did that, but hey, we're trying our best, and these things are going to happen". Are people really going to accept that? That's simply not going to fly.
