TLDR: Flock is moving beyond fixed roadside cameras, into drone surveilance.

With a fixed camera, you might be able to alter your travels to avoid it. In practice that is hard due to how many there are. But you can try. A drone can be anywhere. You prob won’t even know it is present most of the time. You cannot change your routes to avoid it.

We now know that Flock does not log only plates. It also IDs pedestrians and cyclists, ppl on scooters or skateboards. It seeks to build a complete picture of the movements of a whole population.
