Tesla autopilot instructions demand that a driver keeps his hands on the steering wheel. I wonder if Tesla can determine whether Brown did so.
I don't think it's relevant. Unless he needed to steer to avoid the accident it doesn't matter. His foot needed to hit the brake. Here are the situations and their avoidance strategies:
1) Autopilot: Foot to brake
2) Cruise control: Foot to brake
3) manual driving: Foot to brake
So why is this an autopilot issue?
