From a recent Post article on the subject:

Think there’s no such thing as too much parking? Take a look at Tysons Corner, where there’s more parking than jobs, more parking than office space, more parking than in downtown Washington.

Using Google Maps BeyondDC plotted out land used for parking (red) versus land used for everything else (not red) in what is commonly considered the most central part of Tysons Corner.

Is it any wonder Tysons is choked in traffic? How could a place laid out like that possibly be any other way? It is no way to build a city. The Silver Line, and redevelopment associated with it, cannot happen fast enough.
