Flock, and other ALPR companies like Axon, Motorola, and Verkada have been adding capabilities to gather signals from airpods, smart watches, fitness trackers, even toll lane passes.

There were allegations too about TPMS. That is harder, b/c TPMS do not xmit actively. The power comes only from reflecting a received RF, so it is weak. But it may not be impossible. The car itself gets the signals like that, tho shorter range. There may be a larger antenna on the roadside than your car uses, to capture weaker signals. Unclear if it’s possible. But unclear it isn’t!

TPMS started in 1980s. It didn’t get real widespread until 2000s. But even “older” cars, safe from online telematics, still may have TPMS. If there is any way for Flock and the rest to use it as a fingerprint, they will. TPMS has a unique ID.

So I started looking. Can TPMS be removed at home? Answer is, kinda. It’s a little hard without special tire equipment, and it may fuck up the tire balance. A shop can do it, but IDK if they are legally allowed to.

But would that do anything for you? TBH I doubt it helps much. The ALPRs use so many techniques. Plates, ofc. Also scratches. Dents. Bumper stickers. Trailer hitches. Ski racks. Window stickers and passes. Any distinguishing aspect of the vehicle. There are even rumors they can use FR on the driver, but IDK if that has been substantiated. So TPMS delete maybe not worth the squeeze.

Even avoiding ALL emissions, portable devices and TPMS, the ALPR can still ID you in enough other ways. Optical side harder to defeat than radio side.

Once, we could drive without private companies recording everywhere we go. We could even travel from state to state. No papers.
