wow, now what does it do when I leave my radar unit off until I see you speeding, which is what is required for me to stop you anyway...then my little thumb turns the instant on function on to record your speed??? when, we are really in the mood to catch someone at a particular speed, say 70+ in a 55...I won't use my radar until I see someone moving in what I think is 70 or above, then pull the trigger...and laugh as the front of the car dives into the pavement...now, that was kind of mean, so I will lighten up a little and tell you when you think your detector has saved you, actually the officer either isn't interested or is already busy with someone else...as for the fast guy out front, most people refer to them as "Bear Bait"
