Automatic number plate recognition, or ANPR, is a mass surveillance method that utilizes optical character recognition to “read” vehicle license plates in images taken by designated cameras. Used by law enforcement and for electronic toll collection, ANPR systems can store images, license plate text, and, sometimes, photographs of drivers, leading to public concerns about government tracking and misidentification. Modern ANPR systems are capable of scanning plates on cars traveling how fast? Discuss
