That's true for the occupants of the vehicle but the dangers of those outside are greatly different. I'm not saying that planes will never be flown autonomously however there are a lot of hurdles including convincing the public.
If a car when parking is out by 1% it's maybe sticking out of the space and causes other people to have to park badly too, if a plane rounds incorrectly or a sensor plays up and is 1degree out (so even less than 1%) it lands onto of a terminal filled with tourists.
Even as a professional programmer I tend to trust unknown programmers less and less, bugs get uncovered too late, shortcuts taken... online e-commerce fine, cars and busses - maybe but scaling up the trust and risk involved is difficult.
