also youve got to be carful when driving round town, in Kettering, Daventry, Corby and Northampton (all i know of) they use CCTV cameras which are situated in one way streets to check tax, mot, registered owners and police PNC and FIS records, the picture then goes through to the ANPR (Automatic Number Plate Recognition) control room where all these details are run through a computer, comes back with the results almost immediately
in addition to this, ANPR teams around the country have got Spectrum vans which to the untrained eye just look like normal Transit vans which can check both sides of the road, they work on the same principal as the CCTV system except they can go anywhere
