I believe it’s mainly main character syndrome. Like when we play a game like GTA, you care more about your own stats, progress and wealth, and maybe that of other players, but couldn’t care less about most of the NPCs, and that gameplay dynamic seems attractive to most people.
Another way to look at it is the higher up on the perch you are, the more everyone else looks like ants. You probably won’t intentionally leave some sugar for the ants, but if they get a few you don’t mind.
As for the richest of the richest of the rich, they need to stay influential for various evil reasons.
I think e-cars are more computer-like as they’ll prioritize optimizing as much of the system as possible to maximize battery mileage; performance/riding experience as a live service; DRM; probably pretty hackable.
Driverless autonomy could also potentially turn pedestrian cars into part of the public transport system if people can have their idle cars work like taxis (not sure if this would involve things like smart contracts), but unfortunately it seems like the actual last piece of the puzzle that car companies aren’t gonna crack any time soon.
