RFIDs in the tires are a stretch but what about your RFID toll tag ID? At least here in north Texas, all tollways now use electronic billing systems, either by snapping a photo of your plates or via an RFID tag attached to the windshield. Drivers who opt for the tag are given a discounted toll rate. Coincidentally, the tag now uses a non-removable adhesive to attach to the windshield. (they used to use velcro strips so you could peel the tag off and put it in an EM-isolating bag in your glove compartment when you didn't need it)
