"Cundell's car has one ANPR camera, mounted on the front windscreen. Its footage appears on a screen on the dashboard; as a vehicle comes into the frame its numberplate is outlined and read. If there is a "hit" from one of the several databases the system checks against, an alert sounds and details are displayed onscreen."

I was tootling along in Aberdeen one evening and a brand new unmarked Beamer behind me started flashing lights (no siren) and accelerating past me as its ANPR camera had clocked such an offender not too far away and was a doing a u turn and going back for the "kill". Next second...smash....it had accelerated into the car in front of me that was turning right. Clearly the police officers fault......I had to submit many statements on that one...
