Agreed, to many people see radar detectors as an impenetrable force that will keep them from ever getting a ticket. Many fail to relaize that cops are trained to Pace cars, use stopwatches etc… I know someone whos gotten pulled over when his radar detector dident go off but a cop was using a stop watch and determing the speed based on time taken to get between 2 points.
It will hold up in court, althought it can be a fine line at times as there can be user error.
Anyways that and Laser detection everyone loves to think that oh I cant get pinned I have laser detection. Yeah well laser detects only tells you that your fucked. A laser doesnt emit a damn thing untill the cop has your car lined up and pulls the trigger, by that time your fucked
