It’s actually even easier, your car has a plate on the front with a unique ID that a camera scans, often to automatically track your park time for ticketing.
I can’t really care about obscure Bluetooth tracking when every business has CCTV doing facial recognition.
Also, you can read the plate from much farther away than the TPMS sensors.
Yeah exactly, with a car I would no longer be expecting any type of privacy, sadly.
Here in Holland we must even have a mobile phone module in every car so it can call the emergencies in case of a crash.
