Years ago while operating hand held RADAR, I would not stop you unless you were at least 15 over, and if I could not write a citation every 10 minuets it was non productive and I would change locations, I never had a problem with goal achievement. Once while driving the speed limit on a country road I had about 15 cars behind me, the last car decided to pass all of us, problem for the driver, the oncoming car was a sheriffs car with moving RADAR, Bahahahahaha.
