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.
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.
Also, you can read the plate from much farther away than the TPMS sensors.
