Hahaha... fun experiment. Next time you're driving in DC and you see someone making a boneheaded driving maneuver (ie, driving way too slow, not using turn signals, cutting you off, going the wrong direction down a one-way street, parking diagonally to the curb when they should be parallel parking...), make a note of the license plate. 9/10 times it's a MD plate. Nothing personal, just what I've seen.
