Woohoo, the UK's to get RFID-enabled license plates to identify UK vehicles. I particularly like this comment by the amusingly-named 'I did Jane Doe': "Got nothing to hide? Then please post details here of your tax records, how much you earned, where you live, where you have been over the last year, how many sexual partners you have had in the last year. If you don't want to post this then SHUT UP with the 'nothing to hide, nothing to fear' nonsense."
Of course, to complete the Orwellian analogy, we need to follow people around, keep a record of everything they do, then BEAT THEM ROUND THE HEAD whenever they do something I don't like. Maybe body tackle them if they get to close to my house and make sure they can't use one of their legs again (they can still get places, but they've been successfully deterred from entering my territory ever again).
Also shoudl be good fun waiting for someone to hack the RFID and the central system database (hey, remote systems are remote - there's going to be sniffable wireless transmissions somewhere along the line), then do as they please.
On a side note... if you design technology to prevent something, but the technology is useless without police to enforce it, then why bother with the technology in the first place?
