Rather than blame a lack of space, steep hills, or quick-triggered parking attendants for these problems, we should blame something else: driveways. As anyone who's tried to park in San Francisco knows, not only are driveways a tease ("Finally, a spot?...Could it be...I think....it is......a driveway."), but their haphazard arrangement also wastes a tremendous amount of space. Because driveways appear to sit randomly in front of houses, the gaps between them are often too small for a car, which leaves large portions of curb space unused - or encourages some, like Svbtle writer Brian Mayer, to push their luck.

But it doesn't have to be this way.
