Additions to the Urban Dictionary: Crosswalk Hovering

Crosswalk Hovering: When a driver, usually out of impatience, edges his car onto the crosswalk in the hopes of either squeezing between traffic to fit in a turn, or to get a "head start" once the light goes green. By doing so, of course, they block the crosswalk lane for foot traffic, and earn themselves a seat in Hell.

The term can also be used to describe pedestrians who hover on the edge of the curb, getting as absolutely close to the street as possible, so that the second the walk signal flashes, they have a head start on crossing the street. Ironically, these people are often slow walkers, which makes me wonder why they even bother.
