On my route to work and home that thing would go crazy. On my 13 mile run I see at least two cars a day parked shooting radar. The other day the Fort Worth Sherrifs dept had four or five guys on an over pass with a radar gun.

Personally I find RADAR detectors a waste of money. 99.5% of the time if you stay under 8 mph over the limit or with the flow of traffic you won't be stopped. And remember they don't need radar to know you are speeding.

You know those little lines in the road. They are set distance and a quick timing as you pass a few of em gets the observer pretty close to what your speed is.
