with a car the other person has a licence for it, which comes with the assumption of at least some basic skills operating the device.

Users with computers? Some people really shouldn't even approach one.

When I'm riding in a car with someone they don't constantly make a wrong turn even though you're pointing right at the right one. They also have an understanding of the language and the location of the controls. If I tell someone to turn up the radio they very rarely rip the rear view window off the car instead.

That's almost as bad. I don't like being in my own car if someone else drives. "Shift mothefucker" I'd say in my head while sitting uncomfortably
