the car is very much american because of the freedom it gives you. but it's not like it's taking commands from outside, it's taking commands from within the car. it needs to react to deer on the road, etc. if it is YOUR car then it's still yours, regardless of whether you're driving it. massive changes to how people buy cars and the idea of car ownership though, yes, there will be plenty of pushback on that
but yes, the transportation industry will be destroyed. when shipping containers were standardized they fought tooth and nail against it. before, they used to unload stuff in basically individual boxes from ships. now it's a lot faster, with a lot less employees, and a lot cheeper. soon it will just be automated. no one growing up right now should want to be a trucker or taxi driver etc as they will soon occupy that niche market that horse drawn carriages do
electric cars also become viable for long trips because you could just use them like getting fresh horses. this is like 20, 30 years from now of course, but a nationwide network that, if you ran out of juice, they'd just transfer you to another car that keeps on driving for you (or automatically changes batteries out of the car, whatever)
