Probably any modern car? OBD-3 was supposed to have a small GSM transceiver in it to relay GPS location, smog emission, speed, allow remote engine-shut-off, misc other things and that was starting to be deployed in 2012 on some cars but then put on hold for privacy issues. My old vehicle does not emit any RF and is OBD-2. Are there any car hackers on here that have hypothetically speaking modded the OBD-3 transceiver modules? <i>i.e. hypothetically spoofed speed, emissions, location.</i> I can't even find a list of manufacturers that have implemented this. SEMA were the group leading the effort.
