- Freeways account for 93% of distance travelled with Autopilot
- Freeways account for 28% of the distance travelled by regular drivers.
- "vehicles on non-freeways crashed 2.01 times more often per mile"
a quick back of the envelop calculation suggests merely driving on the freeway lowers accidents per mile by ~40%, which accounts for most of the difference between Autopilot and regular drivers.

Teslas are on average substantially newer than the average US passenger car fleet and thus have significantly more safety features and driver assistance tech, are better maintained, etc.
If Tesla compared only to vehicles of similar age and class (Audi/BMW/Mercedes etc) their stats would be much less favorable.
Recent statistics released by TüV^1 show that among relatively new cars Tesla competes with Dacia for the highest failure rate among all cars that go through Germanies mandatory road worthiness tests.
^1 https://www.pcwelt.de/news/TUeV-warnt-vor-typischer-Schwachs...
In short: big car brands' cars go through a preliminary check at manufacturers' licensed dealerships, and only after that get sent to the government's checks. It enables manufacturers to fix cars before independent verification so their safety numbers look great. Tesla doesn't have this kind of extensive network for "pre-checks".
Not publishing open stats on test failures? Why is that something the customer would want to pay for?
It also lets Tesla play with the numbers of shipped cars, because cars returned by dealers don't count as shipped.
But look at the recent HN story about the Tesla without a brake pad.
Ok, so this is a check done after the car has been used for 3 years.
So, it's not QC before the car leaves the factory, it's fixing things before the government checks them and puts them into the public stats for test "failures".
If it's just the results of regular dealer maintenance, it's fuzzier.
Some dealers are qualified to perform the checks and also offer to perform a pre check for free. However cars checked by a dealer would not end up on a statistic of cars checked by TüV.
Please don't compare it to high end german cars.
This is what matters. If/when it becomes less often, the case will be made (i.e. driverless doesn't have to be perfect to be better).
- Age of driver
- Specific highways used (congestion, road conditions)
- What is classified as a highway
Overall this is pretty good news for "autopilot" systems. It gives some humans an ego-boost as they clutch to steering wheels like John Henry. It gives others interested in a more relaxed driving experience the confidence that the computer isn't going to kill them any worse than they already do.As in one I can hopefully sleep at the wheel on a late night trip between midwestern US cities.
John Henryism can navigate the suburbs, stroads, and drivethrus. If they achieve a backup safety system that monitors the humans, well, ok great.
But right now, I want long distance automation, and I can handle the messy last mile. Highways are much easier to get uniform infrastructure convergence: some sensors, PSA warnings, better signs + markings + construction notices, etc.
I think Uber making as big a splash at it did sidetracked this low hanging fruit. IMO that was where the bootstrap bucks were, because you would have gotten freight/shipping to pay the cost of the next gen software, and would have provided the impetus for the convergent infrastructure.
Alas, they are obsessed with robotaxis.
(I live in Europe which has relatively good railway network, still I prefer my Tesla as transport method.)
Would you rather do this for a business trip to a 400-500 mile away city:
- fixed time to depart (and fixed for leaving your destination!)
- have to book ticket weeks in advance for a reasonable flight
- no flexiblity if plans change
- pack a small bag
- transit to an airport (parking or cab or whatever)
- arrive a sufficient amount of time in advance
- check in
- go through security
- get on plane, stuck in seat, no/crappy food
- get off plane, go to car rental place
- rent car (not yours, sucks)
- cost: 100-200$, and if you want to bring anyone it's a multiple of that.
- no cell phone, restricted to plane wifi if they have it
- door-to-door is what, 4 hours? Man I hope there isn't a delay....
Or, with self-driving:
- pack your car or minivan to the brim with stuff you need
- leave when you want
- sleep / stop to eat / stop to bathroom when you need it
- full cell coverage / hotspot
- take additional people
- EV cost is like... 20-40$ for the trip if you include wear and tear?
- door to door is... 5-6 hours
If the car is driving for you, it is far less stressful, flexible, much cheaper, especially if you want to take your family.
Trains are a ... bit ... better than airplanes, but still inflexible, surprisingly expensive, won't have your car at the other end, have to haul around your luggage rather than chuck it into YOUR CAR.
When good highway self-driving comes, I will probably never fly anything less than 1000 miles. If I get a self-driving RV that's EV self-recharging at charge stations? Hell I might get rid of my apartment.
Meanwhile, I don't see many people going somewhere 400-500 miles away regularly. Most places seem either much closer or much further.
If money is a concern, you can always take the bus.
You are saying this in a thread about a company that regularly sells features as a subscription and revokes them upon resell, as well as voids warranty if you get it repaired anywhere that's not a Tesla shop. Tesla have entrenched themselves as rent seekers from the beginning.
But until they get built freeway autopilot is nice.
Me too, and my Tesla handles daytime good-weather non-construction highway driving pretty well with just the standard autosteer. I finish a long road trip much less fatigued in a Tesla than I have in any other car. (Part of that is the seats. Tesla really sweats the details of making seats comfortable.)
But FSD is kind of a sad joke. Off-highway navigation only works in particular major cities, the car stops at green lights, tries to turn right from the left lane, etc. And Elon thinks that's worth an extra $15k. Nope. It really isn't, at least for me.
> An estimated 15% of injury crashes and 24% of property damage-only crashes are never reported to police (M. Davis and Company, Inc., 2015), while9% of injury crashes and 24% of property damage-only crashes are reported but not logged (Blincoe et al., 2015). Even with robust data, establishing the statistical significance of automated vehicle safety can be expensive. Kalra and Paddock (2016)demonstrated that establishing that an AV has a fatal crash rate equivalent to the national average with 95% confidence would require driving a fleet of 100 vehicles continuously for 12.5 years.
I presume there's an adjustment for this in the figures you compare to, but I am having trouble finding it, though that may be my own failure so I wanted to ask if you could help me find how that's adjusted for?
It never got accepted for publication because the reviewers didn't think it was significant enough, but I wrote a paper presenting an alternative way to analyse autonomous vehicle reliability data (you'll have to take my word for it, but the reviewers didn't quibble about the results presented, just whether it was important):
https://arxiv.org/pdf/1812.08901.pdf
The major technical contribution was demonstrating that a class of mathematical models called software reliability growth models are a reasonable way to estimate the "anomalous behaviour" rates of an AV system as bugs are found and fixed.
My second point was that using fatal accidents as a way to measure safety is not necessary; you can use more common events such as non-fatal accidents, or in the case of AV systems in development, even the number of occasions the safety driver overrode the automatic control.
> In this study, all disengagement events listed in the company reports were included in the analysis. It is likely that in some cases, disengagements occurred as a precaution by the safety driver, and no adverse event would have resulted if the AV continued in autonomous mode.
Take a look at [1]. It says that:
> Waymo has developed a robust process to collect, analyze and evaluate disengages for this report. We set disengagement thresholds conservatively for our public road testing. The vast majority of disengagements are not related to safety. Our test drivers routinely transition into and out of autonomous mode many times throughout the day, and the self-driving vehicle’s computer hands over control to the driver in many situations that do not involve a failure of the autonomous technology and do not require an immediate takeover of control by the driver.
> To help evaluate the safety significance of disengagements, Waymo employs a powerful simulator program. In Waymo’s simulation, our team can “replay” each incident and predict the behavior of our self-driving car if the driver had not taken control of it, as well as the behavior and positions of other road users in the vicinity (such as pedestrians, cyclists, and other vehicles). Our engineers use this data to refine and improve the software to ensure the self-driving car performs safely.
So effectively, Waymo has secret process, which may change all the time, to decide which disengagements to report and which not to report. There is no way to tell whether the car would have slightly bumped into another car, or killed a child if not disengaged.
Their reports to the DMV do not constitute data, they are PR.
Not trying to single out Waymo, they all do that.

Drivers driving without a valid license, without insurance, under the influence, wanted by the law, etc would have all kinds of reasons to not report a crash.
I also used to know a woman who thought it was nothing more than a fender-bender, went to the doc a couple of days later because her neck was bothering her. Doc sent her straight to the hospital--incomplete cervical fracture, one wrong move and she could have dropped dead.
In some cities currently even if you want to have police respond to a traffic accident, you'd need to wait a VERY long time - they will tell you that unless you need EMS to try and get a safe spot and call for a tow. Some folks aren't willing to wait hours for police to show up to do what, take a report?
I guess this is the classic scenario where human intuition is defeated by carefully presented statistics.
Adaptive cruise control, tech we've had for what, 20+ years? is more than enough for most highways, it takes out ~80% of the stress/boredom of driving, especially since lane changes are minimal and curves are gentle.
The hard parts of driving (aka not highways) are the real problem, as expected. We solved the easy parts in 2000 and who knows if we'll solve the hard parts by 2050.
You know what would be really nice? Something that detects when it's safe and reasonable to suggest turning on adaptive cruise control so I use it more. Maybe something like detecting I've driven a few miles at a consistent rate of speed above a certain threshold.
The hard parts are definitely the problem, but there are lots of easy wins left on the table too.
I definitely hope your car doesn't put it in some hidden menus on the central screen.
The hard parts are the whole point of autonomy.. the parts so hard that humans still fuck up and kill people. that's the ideal of autonomy imo and short of that its missing the point.
I wish Tesla would celebrate that victory rather than double down on lies.
Is there any evidence that they actually do the easy stuff better than humans? I would want to see it compared with cars of similar age and cost driving on similar roads with similar aged people in control of the vehicle. I'm pretty skeptical that such a comparison would in fact be favourable to Tesla.
I don't know what else to advise people who want evidence. The cars are real things you can experience...
In this case, the effect when the data is separated out is that AP is only marginally safer. When they are combined, it appears to be significantly safer.
I'd say this isn't a case of simpsons paradox at all.
If you're still surprised by this you've not been paying attention to how Telsa operates.
Please itemize these "wide range of safety features" for us that other manufacturers do not have or did not have until Tesla innovated them.
> They invest in own crash test facilities. Only Volvo is kind of on par.
Audi owns one, for just one.
https://www.youtube.com/watch?v=9KR2N_Q8ep8
Tesla roll out cars in generations. So just take a $40k Model 3/Y platform was introduced in 2017 and compare it with any car been introduced that year. My friend bought a BMW in 2019 for similar money, it doesn't have half of that. Maybe you can have them but you have to buy extra packages for extra money.
Tesla don't sell safety features for extra price. The only extra feature is Autopilot. But hardware, camera's , lane departure avoidance, blind spot collision warning etc in every car.
You can even take such a simple feature as forward collision warning system. When you drive it is super accurate it uses the same data and models from Autopilot to predict when there is a crash. If your slowing down dynamic is not good or the car in front/back change it dynamics it will warn you immediately. Only this feature saved me several times from collision. I'm not a good driver.
As I said in 2022 there are many car brands that catching up in some cases they doing better. And this is good.
Human is a bad, constantly distracted driver. Technology is the only way to make our life safer.
Forward collision warning became standard in 2016 by at least ten manufacturers: Audi, BMW, Ford, General Motors, Mazda, Mercedes-Benz, Tesla, Toyota, Volkswagen, and Volvo.
Without speaking to Blind Spot, my Audi does similar intelligent things. If you change lanes next to a vehicle or just in front of it, but you have a positive speed differential, it won't activate. If there is a vehicle in your blind spot approaching you but their speed differential to you is low, it will activate later. If there's a much higher speed differential (say they're in a HOV lane, and you're in a much slower regular lane), it will activate much earlier.
And yes for these minor exceptions Tesla offers a retrofit.
Based on what? "Understanding what is around", and "Tesla is far better at understanding the context" - my Audi has never attempted to drive into stopped traffic.
Your vision (and not just about Audi) that all other manufacturers have these dumb, simple systems and no context of what's going on around is simply, and factually, wrong.
My Audi (and I'm not saying they are the leader, I'm just speaking on them because of my experience) has no fewer than 13 radar sensors around the vehicle and will tell me of incursions into the vehicle's "space". It will recognize that some incursions are more "concerning" than others and alert appropriately.
I really have no idea what you mean by "Audi is not super good" about safety systems.
You have proof for that statement?
I drive a 2021 Audi A1, the most basic version. From Tesla's safety page, this Audi has:
- Impact protection
- Structural integrity
- Crumple zones
- Lane departure warning/prevention
- Collision detection
- Emergency braking
The only thing it doesn't have is the blind spot sensor. But, again, it's on an entry-level car that costs easily 10 thousand dollars less than the cheapest Tesla.
Ah yeah, and all that works in Swedish conditions where Tesla's would be blind for a significant amount of time (the sun hanging just above the horizon for a prolonged time, an reflecting from a snowy/wet road).
But sure. As maxdo would have us believe, "it's hard to match what Tesla offers".
Also, if your saying FSD is going finally, finally be properly released this year — I doubt it.
Your strong pro-Tesla bias and your sweeping, unfocused and unsubstantiated allegations against other car makers undermine your argument completely.
Not currently; I just bought a 2022 Jeep Wrangler that doesn’t have anything of the sort.
Suffice it to say, I don't foresee myself ever buying or leasing a BMW or Audi again. Telsa is so far ahead that it probably won't compute unless you've driven one for a while.
That's an incredibly bad example, because in German brands you have to pay extra for basic safety features(famously in the new Polo you have to pay extra to have more than the basic 3 airbags, I don't even know how that's allowed). Look at a brand new Peugeot/Citroen/Kia/Hyundai and you will pay less than what a Model 3 costs and get just as many safety features. Yes, all the stuff that is optional in a BMW - but look outside of Audi/Merc/BMW/Volkswagen and you will find that this stuff is also completely standard.
And humans are infinitely worse when they have to look after a mostly-ok automation. We can’t pay attention to static things for a prolonged time.
But regarding less “clever” safety features, I agree with you.
#1 lesson of buying cars is:
1. Don't buy German cars if you don't have to (or if you buy them, never complain about the price of their optional equipment).
The corollary is:
1". Buy Korean or Japanese cars.
Volvo built their crash test facilities before Tesla came to existence.
I want the controls on my car to constantly change out from under me as much as I want my miter saw and power drill to startle me with a new interface. Screwing with safety critical controls does NOT make people safer.
It is not a goddamn webpage where fking up the fonts will make it temporarily miss some icons.
Today, other car manufacturers are standardizing safety features across their model lineups while manufacturing cars that are a third the price of the cheapest Tesla.
Pretty much every major manufacturer makes safety features standard on the base models across their lineup today.
Perhaps true, but I've seen more people asleep at the wheel in Teslas in the last 2 years (two) than the rest of my life combined (zero).
1. It's not autopilot, by any measurable criteria
2. As the adjusted data clearl shows, it's not that hard to match it. And since you mention Volvo, they definitely match it. They are honest enough though not to call it "autopilot", or "full safe driving" or pin the plame for its failures on the driver.
Of course they have to be monitoring the flight but they can be generally assured that the autopilot won't decide to just fly into a mountain with only fractions of a second for the pilots to intervene.
Example: Traffic Resolution advisories require a 5 second reaction time and 2.5 seconds for any follow-on reactions. This reaction time includes the time to disengage autopilot and also put the aircraft into a climb-or-dive. Studies show that a situationally aware pilot takes at least 2 seconds to start the reaction, and another second to achieve the proper climb/descent. There are other times on e.g. approach, or ground collision warnings with even narrower margins for disengaging autopilot.
Pilots generally know when they need to be hyper-aware with autopilot and so do competent Tesla drivers. If there are issues with the name "autopilot" for Tesla, the same argument needs to be made for aircraft manufacturers.
If a drivers license required as much training as a pilots license then you might have a point.
When the Autopilot swerves into a concrete wall for no reason, you will have 0.5 seconds left to live. Rwacting in the last 0.1 secons bwf9re collision will not save you - you must react in like 200ms.
It is physically impossible to react in time to some autopilot mistakes, stop defending this idiocy.
https://futurism.com/the-byte/tesla-drivers-autopilot-swerve...
In the example video the car starts turning at 40 seconds and passes the barrier at 47 seconds.
Pilots require extensive training (an re-training). The must meet certain criteria to even fly certain types of plains. And they have to go through additional training if they have to switch planes (going from Airbus to Boeing for example).
So, if we're making "teh same argument" for Tesla, then Tesla needs all that to call its system an autopilot.
An IMO important difference with pilots is that pilots are professionals that get trained and periodically retrained on how specific planes and their autopilots work.
Tesla drivers, on the other hand, hear Tesla’s at times optimistic marketing, and may just learn how to switch autopilot on and off without understanding when to use it and when not to use it.
And most airlines ended up cancelling pending orders for the 737 Max and switched to a different brand that didn't play nearly as fast and loose with safety.
It does seem quite comparable in capabilities to the actual autopilot in aircraft. And that’s what’s confusing to people; most don’t realize that an autopilot is a control used by a driver or pilot to reduce their workload. (As a pilot, I am still logging flight time as the “sole manipulator of controls” during the time the autopilot is engaged.)
You know like that claim about human being there just because of pesky regulations and laws. Not because human would be needed.
including the system's assumption that the operator of the vehicle is doing so as a trained professional in that skill, including the extensive continuous training requirements required to maintain professional-level expertise?
Most Cars volvo produced is not as safe simply because Volvo is still making most of the money on Gasoline car, and they are less safe vs electric. Do we need to create a screaming article "Vovlo is deliberately making money on old tech that kills people"? Again volvo is a premium brand, so they don't want to invest more in EV to make your car more safe. They also promote hybrid Cars that has highest chances to catch on fire compares to EV and regular ICE cars.
But yeah, naming of an optional feature is so much more important compares to real tech, crash tests etc. That's a logic media is trying to put in our head. Don't think.
That's... quite a leap.
> Do we need to create a screaming article "Vovlo is deliberately making money on old tech that kills people"?
That would be just that: a screaming article.
> so they don't want to invest more in EV to make your car more safe.
Ah, yes. Because the only way to make a car safe is to make it electric.
1. I was responding to the ridiculous claim of "if you care about safety it's hard to match with what Tesla offers".
This claim is bullshit, and Volvo easily matches what Tesla offers when it comes to car safety
2. Volvo XC40 Recharge, C40 Recharge are the cars that exist, but you chose to ignore them
> Naming of an optional feature is so much more important compares to real tech, crash tests etc.
I tried to parse this sentense, and I couldn't. Are you saying that Volvo doesn't do real tech, or doesn't do crash tests etc.? If so, are you delusional?
BTW, here's Volvo's purpose-built crash-test laboratory: https://www.media.volvocars.com/se/sv-se/media/videos/154740...
Dude, really?
https://group.volvocars.com/company/innovation/electrificati...
In fact tesla is about to release structural batteries cars, that will use battery as part of the cars body, makes it even more safe. Model Y with structural pack will be out in March 2022.
Volvo at this moment promoting hybrids and ICE that doesn't have this features, because it's bloody business. And money is money.
Just compare real actions of Volvo who claim one of the safest brand and Tesla.
> In fact tesla is about to release structural batteries cars, that will use battery as part of the cars body, makes it even more safe. Model Y with structural pack will be out in March 2022.
I'll believe that when I see it. How's the Tesla Semi release going? Especially since structural batteries are still an active research topic that actual researchers think will be in mass production in 5 years or more.
And it can nicely burst into flames that burn for hours on, without any easy way to put it out. I sure as hell would rather have a broken arm over being burnt alive in a steel frame.
That's not actually why.
It's because carmakers are huge advertisers. You get on their bad side, they pull their advertising.
Tesla's advertising consists of Elon Musk's Twitter account, so Tesla gets the reporting the others would get if the authors weren't reliant on the subjects of those stories for their paychecks.
The study seems to extrapolate from this. Tesla has something like 10 billion miles total driven on Autopilot, on a fleet of a million cars.
It covers 5.4 million trips in 3,400 vehicles with digitally collected records and vehicle data and has been independently validated by the Virginia Tech Transportation Institute and Department of Transportation.
I actually wonder if there's another effect: Drivers only eligible for beta FSD if they meet a super high safety score (which isn't a perfect metric, but probably better than nothing). That incentivizes good driving even when FSD not engaged. Of course, that's a recent thing and hasn't shown up in data.
That's because it's marketing, not science.
Every car company does marketing. Few make over-the-top safety claims about their products. This is the company that decided to have its cars not stop at stop signs. Normal rules don't apply to Tesla.
https://www.bbc.com/news/technology-60230072
"In recall documents, the electric vehicle maker notes that if certain conditions are met, the "rolling stop" feature is designed to allow the vehicle to travel through all-way-stop intersections at up to 5.6mph without coming to a complete stop."
Kind of like in many jurisdictions, police will gently talk to you if you drive 60kph on the freeway, or even if you're doing 90kph in the left lane. Yes it's legal, no it isn't safe.
And 5.6mph isn't rolling. That's beyond a walking pace. That's jogging territory. Any cop watching an intersection would ticket this.
But let's make it real, and let's ask a question about the real world:
Does that mean that expectation is all automated cars will go exactly the speed limit on the left lane of North American superhighways?
If so, those cars will inherently be a danger to life and limb. I don't care about any self-righteous driver who indicates houghtily "I drive speed limit on left lane of American super highway", I've spoken to advanced driver safety instructors, highway police officers and city councilors who all agree those people need to bloody well move it along - it's just not safe.
It’s already against road rules to stay in the passing lane when cars behind wish to pass, regardless of the speed limit, or if you’re already driving at it. If cars behind desire to overtake, give way. This is already codified. No need to blame the cars or the self-driving tech. It’s the human driver who bears responsibility for what the car does or doesn’t do, as are the only ones able to countermand the autopilot. Blaming Tesla for any of that seems like dogpiling and behind the point.
Studies show that, adjusted for congestion and weather, SF Bay Area drivers have some of the highest accidents per mile in the country.
That sounds really unsafe and surely must make driving much more stressful than it needs to be.
People have been saying this for years yet Tesla is not being sued into nonexistence. Presumably their contracts are written well enough that if the user tells the car to go above the speed limit that's on them.
In the vast majority of states this would also be illegal. If Tesla decides it safe, they should be able to just rewrite the rules, though, right?
Most cars idle at 5 to 6 mph, so any roll through a stop sign is likely to break the 5 mph mark.
> Any cop watching an intersection would ticket this.
Not sure where you live, but this is absolutely not the case where I am. I have only ever once heard of a traffic officer ticketing for this. On the other hand, I see cops watch on as people ignore "no turn on red" signs and let them get away with it pretty much every day. Let alone rolling through an intersection at 5 mph.
(Part of the reason I do it is because as I age I would like to ingrain habits that will make me a safer driver even as my cognitive ability declines.)
Near me there is an intersection where the same cars drive through on a daily basis and where the drivers have habituated themselves to rolling stops. Yes, it's almost always fine. But I have been almost T-boned twice, and was hit once, fortunately with minimal damage. And even though they do not have the right of way, their habit of rolling stops regularly pre-empts the actual rules of the road, and they cut off drivers who have the right of way.
That this is due to the normalization of deviance is abundantly obvious.
It should be obvious that your advice is not in any way useful or actionable. And rituals are a very well accepted strategy for dealing with situations which demand consistent and good attention, where human cognitive variability causes problems.
A couple of famous examples--checklists used by aircraft pilots, or the pointing rituals used on Japanese railways.
Doesn’t matter if it’s because of lack of sleep, work stress, cognitive decline, etc.
For some reason I still remember this story decades later and always come to a full stop at stop signs, that's how I was taught in driving school and that's how I will always do it. I'm a calm driver and I don't care if people are annoyed by me, I will drive the speed limit and I will not rush anywhere, it's not my problem that someone else needs to speed because they woke up late, safety should be the number one priority when you're operating a vehicle.
D) If your only defense is the faint hope that the cop doesn't show, the judge is going to rain hellfire on you for wasting everyone's time. Court costs. Amended tickets. Contempt. Unless you are about to lose your license, you don't want to roll that dice. If you go to court to fight a traffic ticket you better have an actual defense.
I’ve won many (outright or gotten reductions to non-moving violations) and lost some, but I’ve never had a judge “rain hellfire on [me]” or anything even remotely similar to that, even in cases where I pled “not guilty”, listened to the state’s case, and presented no argument in my defense.
* I got a camera ticket in Switzerland on a business trip that I did just pay rather than traveling back to appear and undoubtedly lose.
Or they switch between night and day shifts, like lots of nurses do.
They’ll make it work.
I wouldn't hesitate to break traffic rules at 4 o'clock in the morning if there was zero risk of harm - especially while bicycling I'm very flexible, but I also wouldn't complain if I got fined breaking the law. The law must be upheld even at night.
IDK about the US, but in France the speed limit is a target speed; if conditions are good (weather, visibility, traffic) you're supposed to drive at or near maximum speed. It's illegal to drive too slow, and there's a specific fine for this.
https://www.legifrance.gouv.fr/codes/article_lc/LEGIARTI0000... [in French]
It doesn't say that the speed limit is a target, or that you're supposed to drive at or near it.
It doesn't matter. People have all kinds of things they are taught about driving from their parents, instructors, and even official documents that don't carry legal weight (e.g., a highway patrol website).
Even when these types of ideas are good ideas, they aren't binding and you can't count on others to follow those rules. The only true rules of the road are the subset of the laws that are enforced; where enforcement might be done by law enforcement officers, civil judges, or insurance company adjudication processes.
You can get ticketed for driving too slow, but I’ve never seen it. I’ve only seen a minimum speed posted on an interstate (45 mph (72 mph)), but conceivably you can get ticked anywhere for impeding the flow of traffic.
I have (very gently) forced a car off the road once in Germany with the police on 112, a very elderly gentleman was doing 30 Kph on the autobahn and caused one near miss after another. Police came and helped him to get home, we talked for a while and it turned out that it was his first trip in a long time to go and see his sister in another town, he'd gotten lost and was frightened out of his wits by all the traffic zooming by.
I don't know how it ended, he probably kept his license because clearly there was no officer around to witness the event but I'm pretty sure he avoided the autobahn after that.
- not exceeding posted speed limit
- appropriate for environmental conditions
- your ability to safely control the vehicle
And failure to do so could be fined.

It's a driving profile which must be turned on that implements behavior extremely common among the driving public. My Honda with Traffic Sign Recognition and adaptive cruise control lets me set the speed above the speed limit, too.
Our traffic laws are in many ways ambiguous, such that even the police officers enforcing the laws will readily admit you're allowed to drive above the posted speed limit. When traffic rules are interpreted ambiguously, it's not that strange for a driving profile to do the same.
There are definitely places where it isn't safe to roll through a stop sign, unfortunately in the US the system uses stop signs as a kind of traffic calming measure so then there isn't a clear way to mark the places where stopping is absolutely needed for safety. Of course in theory drivers should be able to notice the lack of visibility and drive accordingly but in practice the hazards can be somewhat subtle and many drivers have poor judgement.
