nothing. And banning ALPR wont fix anything either. All cars have 4 unique serial numbers broadcast via radio at all times via the TPMS system. you don't even need a camera, just a radio receiver.

TPMS doesn't need to be unencrypted like that, although many car manufacturers do like to save a buck.

If you get a car old enough, you won't need to worry about TPMS (but that car will not have been tested against recent crash test scenarios).

Ideally the implementation would be immaterial to a ban. The ban (or more likely first, warrant requirement similar to cell data) would be on the tracking database, not the details of how the tracking was accomplished.

Mine doesn't.
