The ANPR system covers the majority of the country already. Every journey made on motorways, A-roads, towns, cities and and ever-increasing number of back-roads, the numberplate is logged and the information stored for ten years on a database accessible by the police.
The system has been working nationwide since last summer iirc, but the concept is seriously flawed. Average joe gets his movements tracked and logged everywhere they go (I think this is a MASSIVE breach of civil liberties, but thats a whole other thread where people jump in with "Ive got nothing tohide so im in favour of it" type statements...) but the uninsured, untaxed cars continue to use the roads with impunity. Why? There are less and less actual coppers to catch the drivers in the act, and the cars cant be traced through the database as the huge majority of these cars arent registered to their real owners.
Criminals simply steal numberplates and clone cars and go about their business with a tiny chance of actually being caught on the road, while we, the honest public, are scrutinsed as if we were criminals.
The next logical step in this system is the much-talked-about road pricing schemes where cars are to be fitted with black-box gps units and you pay as you drive according to usage. Obviously fooling or removing the gps system will be impossible as the ANPR system will ALREADY know your movements and if the two dont tally, questions will be asked.
After that, Its only a matter of time before a slight modification is made to the system to allow automatic speeding fines to be issued without the need for Gatsos.
Cheery thoughts eh?
