Anyone know the drill -- do's and don'ts -- for contesting a speeding ticket in DC? I got singled out of some faster-moving traffic for 47 in a 25. Although I don't know how fast I was going, I do know that the 3 series who passed me on the right and left me behind could well have been doing at least 47, but the cop looked up and saw my Z4 instead. I love the car, but it draws WAAAY too much attention from the wrong people! Any advice would be welcome. Thanks in advance.
