Thanks for that link. I didn't see the unedited video since it's hidden on Twitter.
Two things to point out:
* The main video clip where he engages autopilot at 39mph is clearly a different run/different clip. Not inherently bad, just a bit weird and seems to imply he enables autopilot substanially earlier than he actually does in the unedited clip. I don't know why he would activate it so late and it's possible that affects the outcome slightly.
* The disengagement is clearly from him jerking the steering wheel. You can see him jerk the steering wheel left slightly and the autopilot noise happens precisely timed with that.
Neither of these are really meaningful to the end result I suppose. By the time he jerks the wheel to cause the disengagement it definitely does not have time to stop in time and wouldn't have affected the outcome of crashing into the wall.
That said, I think it's not particularly a fair comparison to compare basic Autopilot instead of their FSD software. Something like the dense fog or heavy rain cases could have had different outcomes for FSD since it slows down in adverse weather conditions. I'd be interested to see how more standard TACC/lane keep solutions from other competitors fair in these tests. I suspect most would also fail these.
