Horse and cart
Yet people HAVE been prosecuted for being incapable / drunk etc with horse and cart.
Planes have good auto pilots. Automated take off and landing was demonstrated more than 40 years ago I think. Pilots can't fly if they are drunk. A plane is in many ways less difficult than a car.
Prove the technology with trains, then planes, then ships. Then trams. Cars and trucks should be last, not first. Exactly what is the motivation?
