Yes, but there's a big difference between a one-time demo under ideal conditions, and something that can be mass-produced and used daily. In the case of tires, (1) the car is likely moving, (2) the tires are spinning at the same time, (3) there are 4 tires (at least - not to mention shoes, credit cards, etc.) and all RFID tags of the same frequency will respond to the reader at the same time, making it very difficult to capture the ID of a single tag. There is no collision avoidance in the transmission. Yes, I'm sure some special technology can be developed that can track and follow a single car as it travels down a road, and isolate the tags, but the police already use ANPR to identify amber alerts, stolen vehicles, unpaid fines, etc. ANPR systems cost under $200, and some (according to Wikipedia) will work even if the car is traveling at 120 MPH. It makes no sense to attempt to use RFID for tracking cars.
