Tire Tracker

Michelin is planning to install radio frequency ID (RFID) tags in each of its tires. The tags will be capable of reporting tire pressure and wear information to a vehicle's computer, via short-range (two foot) transmissions.

But there's another side to this. If each tire has a unique signature (which they almost undoubtedly will) then they could be used to track a vehicle. Sensors in or near roadways could record tire signatures as cars pass by. Our vehicles are going to start leaving a data trail wherever they go. Are we ready to accept the consequences?


The folks at Metafilter are discussing this now.
