Ford this month was granted a patent for an autonomous police car. This autonomous police car will not replace the officer sitting in the car, but it will be more of an assistant in helping the officer. The A.I. will decide accordingly whether or not a driver has violated a traffic law. The autonomous police car will have several LIDAR and sensors embedded in the vehicle. The sensors can detect and determine if a violated a law. For example, a warning or a speeding ticket, the autonomous police car can just capture an image of the license plate.
This figure shows how the autonomous police car may communicate with other vehicles on the road:
Again this patent does not mean Ford will intend to use this technology in its current range of police cars. However, it may add this technology in the future to help assist an officer in stealth mode, if need be.
