I can't remember the link, but there was an article that took satellite photos and showed how much land was taken up by parking lots. It was something close to a third or a half, using places like downtown houston as an example. Also many roads sacrifice 2 lanes to street parking. A townhouse I lived in pretty much sacrificed %80 of one floor for the 2 car garage.

I agree the NIMBY policies are pretty horrible. 8 story apartments should of been a by right development type ages ago. European cities who take up the parking lane with huge sidewalks are very nice, all of this space for outdoor seating.
