I just got pulled over in DC yesterday, by get this, the Secret Service in front to the White House. I was let off with a warning that "It would behoove me not to pass a marked police car that is already doing 40mph in a 25mph zone" I shit you not. My 4th warning here soo I think I will be using Metro more.
How do you not get a speeding ticket? Dont speed or at least dont do more than 9 over and stay out of the left lane.
Back to the topic, if you live in a police state like VA/DC that has ridiculous speed/red light cams check into a detector that can down load live time traffic cams.
