An ALPR doesn't know who's driving.

You don't need a valid drivers' license to renew a car registration in most areas.

In most US cities the cops won't even pull you over if you don't have a license plate, much less track you down and impound a vehicle.

If the registration is to someone without a license, they’ll definitely pull you over. Seen it happen in a couple cities now.

But sure, some cities won’t even do felony warrant service.
