This is the nightmare scenario for me. A forever subscription for the usage of a car.
Subscription for self driving will almost be a given with so many bad actors in tech nowadays, but never even being allowed to own the car is even worse.
Subscription for changes to maps and the law makes sense. I'd also pay for the latest safety improvements (but they better be real improvements). However they are likely to add a number of unrelated things and I object to those.
I think this is purely psychological. The notion of paying for usage of some resource that you don't own is really rather mundane when you get down to it.
