Tire Pressure Sensors Broadcast Unique Car IDs Without Encryption

Dave Troy connected a radio dongle to his computer and monitored neighborhood traffic for an evening. The setup captured transmissions from tire pressure monitoring systems, which send uniquely identifiable data while driving. He posted the results along with an AI analysis of the captured signals. Replies noted that similar tools like rtl_433 can decode other ISM band devices including weather stations. One observer compared the continuous broadcasts to license plate imaging by cameras.
