If there is a circular onramp that gets you on the freeway, and a cop is on it and zapping people as they go by, how effective are any of these radar detectors? Or will you only know before its too late?
Oh, and also, what method do cops use to 'get your speed' when they are facing the same direction you are, and are under a 'bridge'. Does he turn his head around and point the gun through the rear windshield or something? lol
