I mean, this is just wrong.
Autopilot on a plane does actually drive the plane. You can go as long as hours without any human input requirement. Pilots can eat, go to the bathroom, what have you.
Of course we have two pilots, just in case, but this isn't necessary - some countries are pushing for one pilot because the vast majority of flying is done by the plane.
That doesn't mean that autopilot systems on planes are more sophisticated. It just means that automating a plane is much, much easier than automating a car.
We also have fully autonomous trains.
