The only problem with your argument Ben is that airline pilots go thru extensive training to learn how to operate their autopilots. Maybe there should be required training before you can use it? I install auto pilots on boats every week, I go thru a introductionary sea trial on every one I install. I have had customers think they can literally go hangout with the family and not pay any attention to the boat. Can the auto pilot do this and run accurate routes, absolutely, I use 3 axis heading compasses and 10 hertz gps antennas and radar to check if the chosen route is clear. Probably, the same technology the Tesla is using, the problem is, there is a human incharge of the system and we aren't perfect. Training does help though...
