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.
"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."
I mean... I am "Tesla Hater" in that I don't like the direction they're proceeding in; but every human being I ever met in real actual life does rolling stops under some conditions. Last time I can confidently state that "I never rolled through a stop at very slow speed" is when I was 17, and only NOW do I realize how much of an annoying bum I was :P. So if a car does a rolling stop through a stop sign when there are no other cars obstacles or people, my thought is 1. yes that's a breach of law as written 2. It's what everybody else safely does.
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.
It is one thing to note that humans regularly break the law. It is another thing to task people with programing a robot to break that law. I'm very sure that many people break the speed limit regularly. But I would never expect to get away with programing a car to break that limit. No sane person would ever tell an employee or customer that rolling stops are OK, not in writing.
And 5.6mph isn't rolling. That's beyond a walking pace. That's jogging territory. Any cop watching an intersection would ticket this.
I fully support the noble notions and idealistic ideas.
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.
> Does that mean that expectation is all automated cars will go exactly the speed limit on the left lane of North American superhighways?
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.
That depends on the jurisdiction. In my state (MA), I can use the left lane while passing other traffic even if there is traffic behind me who wishes to go faster than I am.
I don’t think that is contrary to my point or what I was trying to say. The left lane is for passing cars in the right lane, and for turning left across traffic in cases with no middle turning lane. The left lane is not meant for driving. I don’t think this varies by jurisdiction and may not be a regulation per se, it’s just the norms and rules of the road.
Yes. For a company to program illegality into a product opens them up to untold liability. Normal car companies program their speedometers to read slightly high (5% ish). This keeps them from being into lawsuits by people who claim that an inaccurate speedometer contributed to the severity of a crash. Any car company who programs a car to drive faster than the limit will be either liable or have to pay lawyers in every crash involving such cars. Even if their car doesn't cause the crash, the fact that it was speeding will contribute to the severity of the accident. It would be like programing a robotic bartender to serve kids who are underage but look old enough to pass for 21. Corporate lunacy.
>Yes. For a company to program illegality into a product opens them up to untold liability.
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.
Because incidents involving these programs are very small. At the moment there are very few Teslas on the road in comparison to other car companies. There would statistically only be a handful at most of such accidents. But give it a few years until there are 10x or 20x as many teslas on the road. Then the class actions will start. That is if, like here, Tesla hasn't already recalled all such vehicles.
There's a difference between the driver setting the cruise control above the speed limit, and a computer unilaterally deciding that it should run a stop sign.
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.
Lol, I live in SF. I've seen two cruisers waiting at a red light watch a car go right through it and do nothing. I'm not complaining or anything, but that guy is defo wrong that cops will ticket anyone.
On a public road I almost always come to a full stop, and if I don't I recognize it as an error. That's the law and there are very good reasons for it. It's an unambiguous standard of performance, for example. Arguments for rolling stops based on personal utility are selfish, IMHO, and arguments pleading utility to others are disingenuous--the rolling stoppers say that it's safer to rolling stop because of the rolling stoppers? Please. Think it through. :-)
(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.
One thing that pops up into mind - I wonder if there's a difference between drivers of automatic vs manual gear shifts in propensity for rolling stops.
I'm struggling to respond constructively to your comment. Think about all the phenomena that make up "cognitive ability" and all of the possible dimensions and properties of "cognitive decline".
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.
When I was a kid and we were living in Vancouver, my mum told me how she did a 'rolling stop' through a stop sign at 4am in the morning with empty streets, and a cop car noticed it and gave her a massive fine. She was in tears because my family wasn't earning much money at the time.
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.
A) Cops don't work such shifts for the weeks/months it takes to get a court date.
B) Cops don't normally "show up" in traffic courts. They can often appear via electronic means.
C) Cops have great respect for courts. If called, they show up.
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 shown up to contest all but one traffic ticket I’ve ever received*. It’s up to the state to prove what I’m being accused of; I am not required to admit to it or passively pay the fine without appearing if I choose.
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.
In this case you should go and ask the judge for a smaller ticket regardless. Getting a ticket so large that we are talking about it on hn 40 years later? Go to court.
Those are traffic cops working daylight hours who pull over many cars and it makes sense to stack those cases. We have a 4am case with a very high bill. If the officer keeps that shift chances are they are not going to want to show up 9am one day before going back to nights the next.
It may not have been. Can the case be made, is there proof, will anyone show up? Contesting a fine takes time but the judge can reduce the amount if it was unusually high.
enlyth's mother did say she rolled the stop sign, so unless she's lying, it's clearly a justified fine.
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.
I wonder if that might be a function of how roads near you are designed. I live in the Bay Area and there are definitely certain roads and intersections where I don't feel safe not coming to a full stop and looking both ways. It might be because of hills or that the other direction has no stop sign, etc. Maybe where you live roads have better visibility but at least in my experience in my part of the Bay Area, I often find myself needing to be very careful at some stop signs and has consequently been doing complete stops.
Some people have never seen sidewalks, tall hedges, or kids riding bikes on said sidewalks blocked by said tall hedges, because they don't exist in modern suburbia, particularly in certain climates.
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.
The law that you linked says that drivers aren't allowed to drive at an unreasonably slow speed, and defines that to be (for highways, with good weather, and just on the leftmost lane) 80 km/h.
It doesn't say that the speed limit is a target, or that you're supposed to drive at or near it.
Yes, but it's how we're taught at driving school. I think it's written down somewhere but can't find it at the moment, so the article I linked to is the closest I could find.
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.
In the US it’s legally a max. I have seen — although rarely — entire lines of cars pulled over and ticketed for speeding on an interstate (limited access, multilane divided highway, max speed 65-70 mph (104-112 kph)) Driving too fast for conditions, is a different fine, so if it’s foggy and you’re going the posted limit, you could also get fined.
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.
> You can get ticketed for driving too slow, but I’ve never seen it.
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.
This is incorrect (which is lucky, because it would both be extremely unreasonable and impossible to enforce). You can only be fined if you are driving so slowly that you are causing an obstruction.
Australian road rules: http://www5.austlii.edu.au/au/legis/sa/consol_reg/arr210/s12... -- key paragraph: "a driver does not unreasonably obstruct the path of another driver or a pedestrian only because [...]
(b) the driver is driving more slowly than other vehicles (unless the driver is driving abnormally slowly in the circumstances)." (Note that these rules form guidance for the States, so there will be per-state differences -- see below)
> This is the company that decided to have its cars not stop at stop signs. Normal rules don't apply to Tesla.
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.
I think there are two arguments here: legality, and actual safety. I would argue that the slow rolling stop is perfectly safe in all cases, but the law exists as it is only to reduce ambiguity for enforcement. It's not a calculated risk - there is no circumstance where it's unsafe.
In the UK stop signs are rarely used, they are in places where visibility is so poor approaching the junction that it wouldn't be safe not to stop.
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.
It is definitely unsafe to enter an intersection where visibility is compromised by an obstruction, hill, or curve. Rolling such stops is dumb even when you don't see anything to stop for.
It could also be that being slightly controversial and possibly factually incorrect is by design in the "any press is good press"/"it's better to ask forgiveness than permission" kind of way. When you are a relative newcomer going against legacy incumbents with much larger ad budgets and fighting to live another day such guerrilla marketing style tactics can be advantageous.
The trick is to realize when you've jumped the shark and are now the established brand and wean yourself of the "fast and loose" approach.
That's because it's marketing, not science.
