NYC has strict parking space laws that work in the opposite direction in Manhattan - i.e. you are not allowed to build much of it. That's a good thing - the core of the Midtown office district has about 700,000 jobs packed into one square kilometer, I'm not quite sure how one would handle that with car based commuting.
Lack of parking space has been shown to be the single most important factor driving traffic in Paris, so the city is busy reducing the overall stock inside Paris. In the long run, we're all dead. John Maynard Keynes
