Not bad, in my opinion. I'm actually a bit surprised the cell phone numbers were so low - people seem to have gotten the idea that there just aren't any cops on the roads anymore and act like it.
I frequently find myself a bit above the speed limit, myself, but I drive carefully in residential areas, and I don't get anywhere near stunt driving (40+ above the limit on city roads, 50+ above when it's 80 or higher).
The fact that they got 30 different cars at impound speeds in just 5 day campaign is insane. It would be interesting to see if those were discrete stops, or if they caught a few at a time racing?
