The actual problem is that autopilot doesn't remove the driver from the situation enough. It gives people the illusion that they can hand off driving to the computer, but in reality they still need to be doing 90% of what they would be doing anyway. They have to stay engaged in the act of driving. Giving people the illusion that they don't have to stay engaged is where I think the problem is. Until the car is driving itself entirely, I'm not sure there's much to be gained.
