It’s literally there so cops etc don’t pull you over for watching a movie while driving.
If the vehicle has a driver's seat and you're sitting in it, you should be considered responsible for the car's actions. If you want to watch a movie, that's fine, don't sit in the driver's seat. If you want your car to drive your drunk ass home, that's fine, don't sit in the driver's seat.
A car at even 20 MPH has a tremendous amount of kinetic energy, and we are all well aware of the destructive consequences of rapid deceleration when large amounts of energy are involved, particularly when fleshy human bodies are involved. There exists no other system with anything close to a comparable level of risk where we do not require or at least expect a human to be actively monitoring the system and ready to take action in the event of a problem.
I'm not saying we should ban Level whatever auto magic AI driving. All I'm saying is that we should use the same standards of responsible operation that we apply to literally every other area of human activity. Why does driving get a free pass?
