I agree it's a problem but I see no discussion of housing costs or the costs of completely redoing public transportation. Clearly the author hasn't thought this through. People drive because they can't afford to live where they ideally want to. In the US, public transportation is virtually non-existent. Without a solution to the housing and transportation problems, there's no way to get rid of cars and no one has even proposed a solution, let alone the author.
