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.
"Because the Origin does not have manual controls, the NHTSA must issue an exception to the Federal Motor Vehicle Safety Standards to permit operation on public roads"
There is a reason that pilots get basically told the ins and outs of a specific plane. Imagine the outrage if people need to do month long training for a specific car just to be able to drive it (and not just a general "here is how cars roughly work and the laws of the road").
Airline pilots aren't supposed to take a nap, and there are occasionally articles about the various things that have gone wrong because the pilots weren't paying attention.
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.
