In the way we use cars there seems no time for graceful handover. You're about the same time interval away from the next car as the time to gain situational awareness, probably less. A plane is usually quite some minutes away from the ground and other planes, or f.e. when landing on autopilot the pilots are not distracted. If you'd apply this standard, the bar for autopilot in cars would be very high indeed. (That might be warranted, although in a risk / reward perspective humans are terrible drivers too.)
