If the pilots are not flying, then it can be just a short time away from a crash. Like when the pilot is not paying attention and by the time the auto pilot can no longer fly, the pilot doesn't have enough situational awareness to take over.
That is very much an outlier, and if it were at all relevant to the issue it would further weaken your case, as these three pilots had several minutes to sort things out. Questioning the assumptions underlying the assumed safety of airplane autopilot use can only weaken the claim that Tesla's 'autopilot' is safe.
