Fanum has a point.
Our government can't use the US system to nail us down on congestion charging, speeding, etc. It must have its own system (or at least one shared around the EU).
We are already one of the most surveyed countries on earth with all the CCTV that we have. Arguably that does good because it's aimed at criminals but the reach that total monitoring via GPS will give the government disturbs me. YOUR EVERY MOVE WILL BE RECORDED.
Our government is supposed to act for the people. So ultimately it's up to the people to decide what they want.
Whatever, do you think the career criminals will put up with that? Won't they be the ones identity-swapping the chips embedded in our number plates? Just how much effort do you think the government will invest pursuing awkward sods like these when they can milk some 'law abiding' citizens with a computer-controlled mail shot?
Or, put another way, do you trust Mr Blair?
