unique serial numbers too, but range is <<100ft with directional antennas
Many tires now have embedded RFID tags, associated with you/your car at the point of sale/installation. These can trivially be read with sensor loops embedded in the road; these have been installed at various points along the highway system "to measure traffic flow".
(Note that I'm not referring to the loops used to control traffic lights at intersections; the "flow measurement" loops are always in pairs, along a stretch of "highway", with a fridge-sized NEBS cabinet alongside. There's even one on the way to Hilo.)
