It may work somewhat like airplane autopilot, but the environments are not comparable. A plane has nothing to hit but terrain which is easily identified and almost all other obstacles in the air are transmitting their position.
In addition, pilots are required to have thousands of hours of training for that specific model airplane. I'm sure the limitations of autopilot come up.
Meanwhile, in most US states, an adult can walk into a DMV, demonstrate the ability to turn on the vehicle and do a 3-point/k turn, and walk out with a license.
That's not that bad, Belgium used to have no driving licenses for normal cars (everyone could drive) and the accident figures were similar to neighbour countries.
It's entirely deceptive.
