    The tire sensors, you mean? (nvm this if you meant the pet chips!) Those do use wireless telemetry. It’s easier do like that, and more reliable, than attaching a wire to a rapidly rotating thing through a brushing contact or w/e. Most of them have little batteries, so they actively transmit. Unlike those pet RFID chips which are powered only by the incoming radio signal.

    They also have unique identifiers. Not unique per car. I guess it makes sense in a way. You wouldn’t want to use the TPMS data from a car in the next lane. But it does open up this attack :(

    I wonder what kinda weird looks a person would get, if they ask a tire shop to remove the TPMS modules from their tires, lol
