I imagine driving a self driving car is like watching someone else driving as a passenger: "oh look, a railroad crossing with a train crossing" "we're getting close to the crossing, surely he noticed the train" "why aren't we slowing down? oh crap he falls asleep at the wheel" *grab the wheel and steer off the road* As long as self driving cars require constant supervision, I think this kind of accidents will keep happening. Drivers will have reduced reaction time when they're not actively driving the car.
