But I guess you don't really care about tracking people who drive cheap cars, for they have less surplus resources for you to convince them to part with so they're less of a priority to track...

Re: Inferring car movement patterns from passive TPMS measurements
#12I built a demo of this back when I worked at Qualcomm in Seattle; match this with WiFi beacons and you can trace a person fairly well. It's been over a decade, but at the time both iOS and Android would send pings fairly frequently to all known WiFi networks looking to see if they should switch to a faster one. With your device ID, list of SSIDs you know, and your TPMS data, a person can learn a lot about you. Like,…
Phones randomize hardware addresses now, so this doesn't work. Although there are better, not-so-publicly-known, ways to do it anyway.

#13Maybe a buying trip north of the border might suit some U.S. folks alarmed by the TPMS blabbermouth data. Although Canadian-spec new vehicles usually have TPMS monitoring, it is not mandated, so some vehicles will display a dashboard icon or menu warning if no TPMS signal is seen, while others will just ignore the issue. Given that many Canadian consumers have dedicated sets of winter and summer tires/wheels, this is…

Pretty sure at least every newish GM car broadcasts wifi and probably doesn't MAC address rotate so there's that...

I live in the Midwest and have a car with TPMS and winter and all season tires and it's a $10 thing to tell the car to pair with tires when I swap them. Most mechanics have these too as they service wheels so it's not an issue really. Yeah it messes with the tracking but my car also has wifi I can't turn off without ripping out OnStar.
