If autopilot starts braking even slightly and it shouldn't, I immediately take control. For this to happen, the driver clearly was not prepared to take control in any way. It's like driving on cruise control with your legs crossed. The automated cruise control and lane-keep on my previous car, an Audi, would occasionally do crazy things too. The hyper-focus on this being Tesla's fault continues to baffle.

Well it’s the only company that charges 20k for “full self driving capability”

This mirrors my experience of driving in America. People do not adjust their speed or following distance to the conditions. They drive like they have some sort of right to a road free of obstructions and to drive at the speed limit or above, no matter the circumstances. It's as if they expect the speed limit sign to adapt to the circumstances. They have the attitude, "Well if I need to slow down, why does the sign sa…

I agree with what you said regarding American driving habits, but that doesn't absolve Tesla from its own share of responsibility. The car that was driving in front of the other lane was not following anything; Tesla swerved into its path, so the resulting distance between the cars is on Tesla. What speed would you expect the other car to maintain to avoid such an accident?

It's a popular opinion but I think it's wrong. If they weren't all so close together some of that could habe been avoided. The Tesla indicated for a very long time telling other what it's gonna do.

The Tesla cut into the lane with 3 car-lengths or less behind it and rapidly decelerated. The two cars behind are going to collide because the first one, who was safely positioned before the Tesla changed lanes, didn't have time to react and the second car was probably not able to either, because the brake lights in front didn't come on until too late. Then, there was a couple cars that were probably tailgating, and…

It’s also just not realistic. If everyone was that defensive (5+ seconds distance) on such a busy road it would severely lower its capacity, leading to constant traffic jams. Leaving that gap will just mean others taking it.

I think this is the thing that makes the most sense. But if I were to bend over backwards giving the benefit of the doubt - is it possible the driver feared resuming the previous speed because they were worried the car saw an obstacle that they couldn't?

Like the article suggests - if you're not fully engaged, it's as if you're driving impaired. And there's so much automated that it's difficult to be so vigilant. Once the car starts braking, how much latency can I afford just assessing what caused it to slow down? How hard is it braking and how closely is traffic following me?

Have you watched the video? Its freeway speeds, a decently busy freeway, at a tunnel entrance that’s curving. Plus the car switched to the passing lane and abruptly stopped. This wasn’t going straight on a highway stopping in the same lane the driver was already in. I can understand how the conditions probably made it worse.

The Tesla car switching and abruptly stopping was a big problem, and I can understand that first car having trouble, but for cars behind the first one they should ideally all be keeping a distance ready for suddenly hitting the brakes in an eme…

That isn't the passing lane as its a bridge (not just a highway) and the left most lane before that area is an exit, so not guaranteed to be the "fast" lane.

Doesn't his car have ABS? Even under heavy braking, the car's wheels shouldn't lock up and lead to swerving. Did the trailer have its own brakes?

I believe you are thinking of skidding, not swerving.

I don't see how the trailer can force a car to swerve without any loss of traction through skidding.

Tesla has much more of an issue with phantom braking than any other manufacturer because they chose to rely only on cameras, and that system simply does not work as well when it comes to this particular issue.

Additionally, how can you blame the driver? Did you watch the video? It's not as if the car slowly stopped. It slammed on the brakes. There wasn't time for the driver to correct for this before the car behind -- which Autopilot had just moved in front of -- slammed into them.

Tesla's Autopilot and Full Self Driving get a lot of focus and criticism for two big reasons; 1) their product names clearly and deliberately paints a picture that the features do not live up to and disclaimers do not fix that. 2) they are unsafe on public roads as they operate today. They are a menace to public safety.

Why would you be shocked and disappointed? It is the obligation of the driver trailing you to maintain enough distance to be able to stop safely if the car in front of them has to brake hard for whatever reason. The fact that your hard braking wasn't actually necessary may mean that you're also responsible, but it doesn't absolve the other driver.

As a matter of pragmatism, the person intentionally putting other drivers at unnecessary risk by being an asshole should bear the responsibility for the outcomes of that intentional and unnecessary risk they elected to subject roadway users to.

They should, and I said as much.

It does not absolve the other person from responsibility for not following the required safety protocol. The car in front of them might have had to brake for a perfectly legitimate reason.

I mean, suppose that the other driver was driving while drunk. They might have arrived to their destination safely without the asshole in front, but that's not an excuse against a DUI ticket.

This is a bug in Tesla's specific meat. Other self driving implementations e.g. Cruise, Waymo have LiDAR which is an additional and in my opinion necessary sensor for detecting objects. Because in this case it sure looks like a phantom breaking issue.

Yeah, it looks like one of those cases where Elon is being stupid - self-driving cars with LiDAR are a lot safer. Anyone know how much a LiDAR system cost nowadays?

Heck, my $400 vacuum robot has lidar and its advantage when navigating are immediately obvious to anyone paying attention. Rather than cost it feels more like laziness - sensor fusion is hard, so let’s just delete the problem.
