All your tires are now monitored. For those worried about Big Brother, look no further than the RFID devices now being implated into many products. Michelin will start embedding this in your tires, so all your car's movements can be tracked. These cheap little devices send out a radio frequency with their embedded ID number. A monitor station can be set up to query and track ID passing by. So, pretty soon, YOU will be able to be monitored by any monitor station! I will have to walk past my RFID sensor sweep everymorning soon.
