I love how this keeps getting repeated by everyone everywhere

it’ll turn itself off before an accident to pass accountability to the driver.

But both Tesla (5 seconds) and the NHSTA (30 seconds) count any incident where a L2 system was on before the accident as having happened with the system active. So no, they do not use it for that purpose.

You know that video going around a few weeks ago where some dude with FSD on darted across the rode into a tree? Well, he got the cars data, and it turns out it was disabled due to enough torque on the wheel which is one of the ways you disable it. He probably nudged the wheel too hard by mistake and disabled it, or there was a mechanical failure which disabled it, but the accident counted as FSD in the report he got from Tesla as ON even though it was OFF at the time of the accident when he started going out of his lane.

So please just stop it with that nonsense.

I may be buying the foolishness of the masses, but your anecdotes are only as good as mine.

what about this one? https://youtu.be/V2u3dcH2VGM

I don't know anything about self driving, but I can't imagine why it would turn off right before a crash instead of keeping the breaks held

(also I know the drivers is a total idiot and it's 100% their fault, I just want to know why it turned off)

My guess is that Automatic Emergency Breaking (AEB) is a separate feature from autopilot.

AEB is something that is always on and watching even if AP/FSD is off, but it's only intended (originally anyway) to turn on when a crash is imminent to slow forces, not prevent a crash. So my guess is AP fails to detect the cop car as radar couldn't see it, vision finally sees it tries to brake but it's too late, AEB detects a crash is inevitable and kicks in which turns AP off.

It'd actually be nice if we got a straight answer from Tesla as to why it happens this way. This would have been reported as ON as it was within 5 seconds, and obviously NHSTA was investigating it as ON.
