Usually the purpose of this event is to get cheap tickets out of people doing 5 miles over the speed limit. This works well since wealthier people tend to have powerful luxury cars which can go very fast without them even realizing it. While claiming to be 'keeping the roads safe', they are merely looking for a cheap buck out of hardworking individuals. Driving in a straight line a little to fast isn't as dangerous as the assholes who switch lanes aggressively, cut faster moving traffic off, and tailgate. These pigs should be out patrolling, looking for aggressive drivers. Of course, if you're driving an expensive car, you'll get pulled over for being the victim.
