I got nailed for expired registration last year via License Plate scan. Another time, 4-5 years ago, I was nailed for Driving While Suspended by the same means.

It sucked because my license should not have been suspended. 3 hours of phone work between DMV in NY and in NJ and I got the letter stating as much 2 days before I got the letter stating that my license was suspended. DWS was thrown out, which blew up their search of my vehicle, but it was either eat a Loitering in a Known Drug Area or go to trial on the CDS and Paraphernalia charges. I paid the $237 and haven't driven in that town since.

If the cops make enough drug busts on a stretch of highway, it can become "a known drug area". Fucking ridiculous.
