Ah, it's another in the broberfett series of 'OMG TEH UK IS BIG BRUVVER' threads. As usual, his title is overblown and ridiculous. The system in question is combining the two existing technologies of Automated Number Plate Recognition with GPS, to create an 'average speed' camera from a relatively simple/cheap ANPR software enabled camera. It's not 'being spied on from space' or 'satellites giving you tickets' or any other nonsense. As the AA, always champions of motorists rights point out, it's a natural evolution of existing technologies, and nicely answers most of the issues people have with fixed cameras, such as the claim that taking a speed at a single point doesn't represent a driver's real performance on the road. This technology would solve that issue through averaging.
And Lindley, it's designed for use in areas like estates used as 'rat runs' to reach workplaces and schools, where motorists charge through residential areas to avoid using congested main roads. It would likely never be deployed on the motorway, there's simply nothing substantial to be gained from slowing the motorways down. The cost wouldn't be worth it.
