I still laugh when I remember that for years they kept saying that the auto pilot was turned off every time some tesla crashed, until it was finally revealed that the auto pilot turns off automatically when it detects an imminent crash it can't avoid.
Do you want the autopilot to keep driving after a crash is detected? Turn off right before a crash is the only surefire way to make sure the fscking engine turns off before the crash which could cause control signals to get fubar and not disengage.
Autopilot could kill the engine and lock the brakes without turning itself off. By turning itself off and giving control to a human mere instants before a crash it's effectively ensuring the engine isn't turned off (as there'll be no time to do it before the crash, and the human may not be in a fit state to do it afterwards).
But more to the point, regardless of whether there's a good reason for it to do that or not, it shouldn't be used to claim on a "technicality" that autopilot wasn't active "at the time of the crash", as clearly it meaningfully was at all points leading up to it.
It is giving control of the car to the driver without enough time for a human to react to anything. I understand why there's nothing the autopilot can do but then blaming the driver for not fixing the situation in the 200ms they have is stupid.
It’s a system that has full blame on the driver to beginwith so what exactly are you trying to say? Driver has blame the whole time. In the fraction of a second before impact, the automated system turns off as a safety precaution to reduce the impact as much as possible.
No, it turns off to disregard legal blame. Everything that the autopilot is turning itself off for right before a crash, is something that not only can be done with the autopilot on, but the autopilot can do faster, safer and better than a human. For as much as counts at that point.
