DrSkwid writes "The UK Police are building a network to monitor the movement of every vehicle in the U.K. through an extensive Automatic Number Plate Recognition (ANPR) system. The data will be retained for 2 years. The Register further reports that the system will likely be used for issuing speeding fines." From the article: "The primary aims claimed for the system are tackling untaxed and uninsured vehicles, stolen cars and the considerably broader one of 'denying criminals the use of the roads.' But unless the Times has got the spacing wrong, having one every quarter of a mile on motorways quite clearly means they'll be used to enforce speed limits as well, which would effectively make the current generation of Gatsos obsolete. Otherwise, checking a vehicle's tax and insurance status every 15 seconds or thereabouts would seem overkill."
