Smile for the camera!

I mentioned last December that the car tax disc is to disappear (as from the beginning of next month apparently) and suggested that this was not necessarily a good news story.  Well now I'm even more certain it's not.  In order to try and identify those who haven't paid their tax, number plate recognition cameras are being installed throughout the country, and whilst this may be considered to be reasonable at first sight, the troubling aspect is that they will record not only the tax dodgers but also you and me going about our everyday business, and this information will be stored for an indefinite period.  Which means of course that if they wish to do so, the authorities would be able to construct a pretty comprehensive record of where you have been and when.  And how do you feel about that?
