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.
How’s that different from just running the hotspot on your phone?
Your phone as a hotspot still uses the data plan, so all the data you don’t want going out still goes out. Using a hotspot eliminates a lot of the background data (set as metered network or use NetGuard, etc)
