A self driving car should have no steering wheel. If it has a steering wheel it is a vote of no confidence from the manufacturer.
Throttle and yoke aren't a vote of no confidence from aircraft manufacturers. Some modes of operation are suitable for autopilot and some are not.
That presents an interesting failure mode challenge.
Well we don't have any self driving cars outside of San Francisco. Only cars with advanced driver assistance.
How do you reverse such a car into your own driveway that's positioned in a funny way at an angle and an incline? What if you're parking off road for any reason? Like, you have to be able to manoeuvre your own vehicle sometimes.
I don't really buy that. There are a lot of situations (e.g. being directed to park in a space at a fairgrounds, ski area, or whatever) that you can't reasonably expect AFAIK to be programmed into a car's computer. Even if a car can legitimately handle roads under most circumstances, they're not going to be able to handle everything.
