Those would be the fully self driving cars. Cars that can somehow navigate short distances to a parking spot where the next person takes over would be the middle step. They sort of act like a valet service or a "self driven taxi" (comes to you where you need it).

A FSD is not worse. Just not better for anyone but the owner unless it's a shared vehicle. The only way we all benefit is if the number of cars goes down because they are shared or people move to more public forms of transport.
