SignalTrace “links devices that regularly travel together, correlating them to license plate.” It is a surveillance product that will sweep up and add all sorts of Bluetooth and other data to license plate readers, linking specific devices—and people—to cars.

      Two ways:

      1. The first is essentially the same thing as the above product, but without dedicated hardware. They can see the precise route you’re traveling and compare that against already extant databases that use security cameras, ordinary highway plate readers or on police vehicles. (They also might just be given it, if you have a car with a SIM card).
      2. This is the real method: they have all your PII already, so they just buy & package it. It’s not like it’s a huge secret - it’s pretty widely available info from insurance companies and data brokers if you’re a big corpo (I think you can also get it with a public records request, though don’t quote me on that).
