I drove through Mississippi a couple days ago - somehow I missed that kind of entertainment. What I saw a LOT was a random SUV on the side or median doing speed checks. (might have been AL and not MS though)

I also remember the small towns south of Dallas that used to do similar stuff on I-35. Made like 80% of the town revenue on speeding tickets. Lasted until TX passed a law preventing that kind of income.
