and how long do you think it takes for the radar to travel back to the police once its hit you ? its already travelled half the distance to reach you before you know it .do you have the relexes of superman to slow your car down quicker than the radar waves can travel?
even if you did, the radar gun has clocked your speed so even if you do slow down theyve got you anyway.
radar detectors work on the theory that you might pick up radar scatter from the car targetted in front of you,giving you a few seconds to respond. if your being targetted your caught.
thats how i understand radar detectors to work.
