The former would work too. Primarily that's just me recognizing that obviously there are some people that have reason to be driving. I'm not sure that mobility scooters / wheelchairs would be adequately handled by all public transport at the moment even in London, there would probably be a lot of repressed demand, or people would just stay indoors. A 60-person bus might have one or two wheelchair spots; a mobility scooter won't go on them at all; I very rarely see either on the trains despite it being technically possible. A lot of tube stations are not step-free. I'm not suggesting banning vehicles; I'm suggesting taxing them appropriate to the damage they cause so that fewer people see "go for a drive through tons of residential streets" as a normal / accepted thing to do.
