Some cameras even have facial recognition so dont even have to be driving or even after you arrive, surveillance continues at your destination to collect more data.
I saw one video of a guy who was pulled over from out of state. They asked him questions they already knew the answer to as they had already had his nationwide travel history from Flock. They were trying to see if he was being evasive as another reason to search his car, which they did.
Data collection, unannounced facial recognition and travel surveillance is out of control IMO and the big money is buying politicians to keep it lightly regulated in most places so they can cash in on your life.
There are movements to remove these cameras but overall the surveillance state is powerful, profitable for collectors and seemingly unstoppable. Its a nightmare for privacy minded individuals.
