-
plate number is tied to a VIN which describes the make/model. (sir, this is a
wendystoyota. where is the honda?) -
replies not required from the plate - plate has a specialized qrcode printed across the entire plate (infrared reflector?) with an identifier (lic + other public info?) and signed with an RSA keypair - reader can authenticate the information and a qrcode read counts as a verifiably good read
-
…or just ship RFID tags in the yearly inspection stickers - same cryptographic concept
none of this is hard or costly. only impediment is public rejection and we all know that can be managed.
