- boardwaalk 5y agoWait, reading or spoofing tire pressure is more of an issue than opening doors and starting the engine?
- montjoy 5y agoPotentially. You could put a dangerously high or low amount of air in the tire and then tell the car, “this is fine”.
- ctoth 5y agoMore disturbing to me is that most TPMS transmissions have a unique ID associated with them making it trivial to track a given vehicle. Many vehicles only transmit pressure when prompted, but I have definitely noticed those which constantly transmit. Usually Toyota.
- mywittyname 5y agoThat's how Toyota's proximity unlock feature works.
- ComputerGuru 5y agoIsn’t the range extremely close?
- kube-system 5y agoTPMS often uses a lower frequency range which can travel pretty well.
- coolspot 5y agoDepends on the size of your antenna. Russians might secretly built 10e10 sq.mi. antenna array field to read tire pressure of all US cars!
- sennight 5y agoI'd say so, from the perspective of utility and persistence. 4 (maybe 5 including spare) uniquely serialized radio beacons make a good target for dragnet surveillance with zero risk to abusers. I'm also more weary of scam extended warranties than I am of kidnap and ransom, even though one is obviously far more unpleasant than the other.
