Well I'm all in favour of ANPR technology, fixed, mobile, and in police cars. It's not just to flag up VED dodgers but more importantly uninsured vehicles and those without a current MOT - and I'm very much in favour of the annual testing of fitness of vehicles.
All the arguments against having an MOT do not outweigh the benefits. Not one.
Virtually every day that I go into Yarmo or Norwich I see at least one vehicle, not always cars , parked with a big yellow notice telling how it had been seized by the police, usually for the driver being uninsured or not having a full license and no supervising driver which means that the vehicle is uninsured and will always be seized.
No "ifs", no ,"buts", and the driver and any passengers have to make their own way to where they were going with the driver facing a fixed penalty of £300 plus 6 penalty points or going to court and the possibility of an unlimited fine and more.
It also gives the police the opportunity to give the vehicle the once-over. Some defects result in mandatory penalty points and big time fines for example 4 defective tyres and straightway that's 12 points and if they're really gnarly then £2500 EACH TYRE!.
I like Safety Cameras, ANPR technology, and MOT testing. They make the roads much safer than they otherwise would be.
