Flock Safety’s core technology consists of automated license plate reader cameras that photograph vehicles as they pass. The system could therefore capture vehicles in places where drivers might not expect to encounter an automated license plate reader. Those questions have become increasingly important as automated license plate reader networks have expanded across the United States. The proposed system was not deployed as a nationwide network of Flock license plate readers operating through Uber and Lyft vehicles. The plan to turn Ubers and Lyfts into roaming license plate cameras never happened.
