I was just driving around in the local area and I had my radar on highway mode. I was sitting at the light and I wasnt paying attention and when the car infront of me moved up about 10 ft or so I stayed back a little and all the sudden I got a laser signal come up and I was looking around and didnt see anything. Well I actually got stuck at the same light so when it became green again, I let the car infront of me go up about 15 feet and when he got far enough, the laser came up again and I just drove up a ways looking around for anything and didn't catch any cops near by or anyone standing on the side lasering. Im not really sure if theres any laser falses. The light I was at was actually right under a highway ramp, so there could of been a cop up the enter ramp, but I said no to that because that would of been a side pickup and there were too many walls. So could someone tell me if theres any laser falsing or any other explanations. Thanks Mike.
