I got a bill recently from NYC for speeding through a red light, which was weird enough as it wasn't a car that I own. But the license plate listed is one I had years ago, when I lived in a different state. Clearly license plate databases even within government are inaccurate. I can't imagine how bad the private databases are. The fact that the government also leans on the private databases seems to compound the problem.
Likewise. I once got pulled over by the police because they insisted that my license plate had been turned in and I was driving without valid plates.
They called other officers, ran the plate, ran the VIN, ran the plate, ran the VIN. I dunno I think we sat there for almost an hour before they told me why they pulled me over and what was up.
