Don't know why I'm being downvoted, there was an accident recently near where I live where a motorist hit a pedestrian in a roadway. He stopped his car and pulled into the opposite lane and turned on his flashers to prevent traffic from running over the guy who was lying in the road. An autonomous vehicle stopped, seeing the car in its lane, but a driver behind it pulled out and passed the vehicle unaware of the pedestrian, running over the injured guy who subsequently died from his injuries.
