I dont know where you live but last i checked, officers have always been checking plates even when your not braking the law. i remember when i was in ohio that a few nearby city police departments got some new scanners to speed up plate checking.
Heck, the 1 of the big spots for plate scanning i've notice is parking lots of big stores (like walmart) and mall's. So you dont even have to be around your car to have the a plate on a car scanned.
