It could have been part of the Automatic Number Plate Recognition (ANPR) trial. On that part of road it would have been going off every minute or two. It detects expired regos as well as cross referencing the registered owners licence (if it's suspended/disqualified/expired). I think it also checks them for outstanding warrants.

:thumbsup: Spot on.
