If the only way to check if a car has been taxed, is insured and has an MOT is ANPR just where are the readers?
Very occasionally we see a camera van on the A36 betwen Salisbury and Southampton. I know Wiltshire Police traffic cars all have the ability to read and check, but again there are only a handfull to cover the county and to be honest they have more important priorities.
But if no one was looking at tax discs anyway I uppose nothing really changes!
I rest my case
