The USA has a nation wide system of vehicle license plate scanning and tracking of vehicle movement. Almost every law enforcement vehicle carries a constantly operating license plate scanner, scanning the license plate of every car it passes, every car in front of it. All these scans go into a central data base.
The scans made by all the independent jurisdictions are placed into the central data base from which various subscribers and those other entities monitoring may use to track individual vehicles.
Processing capacity keeps increasing, methods of linking information taking points expand, new vehicle onboard circuitry communicates with the vehicle manufacturer and insurer and whoever else.
