As far as I know, he doesn't drive; he doesn't need to, really. There are vehicles in his world but as he's lower-class and there is an extreme disparity between classes, it's doubtful he has access to even learn how. If he did have a car, it'd probably be a compact clunker but he'd take as good care of it as he could. That said, I really don't see him driving much. He seems more like a walking or public transit guy to me.
I've seen a few pictures of him on motorcycles but he doesn't seem the type to actually drive one because he's not flashy at all.
…Is it weird that I think that he would care more about maintaining a car and having it look nice than actually driving one, if he had the funds? I think driving would make him nervous but taking care of it would be relaxing to him.
