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.
That isn’t the same level of identifiable as a unique device ID/MAC/whatever though. And even if my devices weren’t the issue, I wouldn’t feel comfortable having an automated system logging my clothes/gait/face just because I’m out in public. Fully automated surveillance such as this ought to be it’s own category.
Also I don’t think you are trying to argue that it is right.
