My dad has one of those...I feel bad for you if you live in a big city, whenever we get into a commercial area, there are always those motion detecting doors, or the alrms on doors incase someone trys to steal something...All kinds of stuff like that, when we get in those areas the thing goes nuts, it picks up EVERYTHING its always beeping, laser...K9...Cband...Kband...you GOT to unplug it or it will drive you nuts...
and glc is right on the cop thing too...its part of their job too catch speeders, it isnt like they need radar to tell how fast you are going...and they are sneaky too, you know why they always ask you how fast you are going when they come up to the car..and you always give them that dumb guess like..uhhh, 70...they always add on like an extra 10mph cause you basically let them know right there and then that you dont even know how fast you were going, and they can say whatever speed they want, cause you dont really know, he doesnt really know, but he thinks you were speding and hes a cop, so he wins...My grandfather was a cop, he told me this
