I realize what you are saying, but as you can see... nobody is slowing down. In fact drivers seem to be getting worse. If you had MARKED dummy cars driving up and down the 404 everyone would be driving the speed limit. The driver doesn't have to even be a cop and doesn't have to pull anyone over. People just see the cop car and slow down.... even if they are already going the speed limit. If an unmarked cop car pulls over 1 car and you see it on the side of the road, people slow down for a split second and then speed up knowing that the only cop car around is busy. I visual police presence if far more powerful the a hidden one. Also, you want to fix the cause of a problem and not the symptom. When a cop pulls over a speeder they are only really putting a band-aid on a problem (they catch 1 speeder). The trick is to keep people speeding to begin with.

Boy I sound old. :D
