An even more serious problem with Tesla's claims regarding the safety of its Autopilot is this: Autopilot failure statistics are non-ergodic. You don't get to "play again" after a catastrophic Autopilot failure. So, Autopilot must not be 5x or 10x better than your own driving -- it has to be, like 100x or 1000x better, in order to warrant you risking your life on it. Trusting an autopilot that is just 10x better than you are? Insane. It randomly drives under a semi-trailer that you would have easily seen and avoided, and you're dead.
