Can't do what other cities have already done? How did those other cities do it, then? If parking starts to carry its cost, rather than being subsidized by government regulation, then it quite likely becomes more economical to rely on mass transit than banged-up hatchbacks. But yes, changing from horribly-designed cities spread out over vast areas that depend on cars to navigate to human-oriented cities with effective mass transit is a huge project, and would require thinking about solutions that take into account the currently-hidden costs of the current designs.
