> Given that planes, which rely on a class of specifically trained professionals with minimum hour requirements, still have issues with this from time to time Most of this issues come from the fact that planes can't just stop in the middle of the road and wait for help, they have to land somewhere and do it fast enough not to be out of fuel. Cars don't have to drive themselves to nearest service center when they encounter any hardware malfunction, they can just stop and unload passengers. Self-driving company would use another car to drive you to your destination (not even necessary self-driving car).
