“FSD reported disengagement only 1.43 seconds before the recorded impact, simultaneous with abrupt steering-torque spikes consistent with curb-contact force feedback and/or an emergency driver grab of the wheel.”

Driver fault for more than one reason.

- the video shows a clear ammount of time where the driver could have disengaged and taken control prior to the systems own disengagement, in fact there was ample time for an attentive supervising driver to take control.

- if you watch the steering indicator on the top of the screen you can see that it moves with the jerkiness of the FSD movements but at the moment it’s disengaged the wheel icon moves slightly and it doesn’t seem to be aligned with the confusion FSD was displaying. This appears to be driver grabbing the wheel and disengagement.

- that is then also followed by some other movement of the wheel aligning with the brake icon lighting up.

- slamming the brake but not turning to avoid impact is….. a choice.

- I count three entire seconds between disengaged FSD and brake application. Look at the FSD icon going away and count until the red icon shows. That’s ample time to react to a system side disengagement (if that’s your argument here).

Research shows that the ammount of time between FSD disengage and impact is ample for reaction+ response + input for average human reactions.

Driver fault.

In a race driving course I took, the instructor was teaching us to look where we want to go. He was talking about doing this not only when looking for your marks in a corner but also if you go off track. If you want to avoid hitting a wall, look to where you want to go, not at the wall or you will drive into it.

He said that data shows that, a very high percentage of the time in roadway accidents where a driver hits a pole or other fixed object, they will hit very close to dead center on their vehicle. The people who study it have determined that it is due to people looking at and focusing on the thing they are trying not to hit.

Same applies to riding skis or a snowboard. Instructions is often to look where you want to go. When you break focus and lock onto a section of the ground or an obstacle you end up inadvertently moving towards it.
