Interesting side-article to be aware of in the Telegraph.

The Ministry of Justice are using access to new technology, i.e. Credit reference agencies, Government Databases and online tracing tools to chase historical fines, some over 10 years old, that were never paid, often where the person has since thrown away any documentary evidence.
Worth a read. Not directly connected, but does show what being a contractor to the Government currently entails, stitching people up for past mistakes because they now can, off the back of so called terrorism "to protect us" / to keep us safe aka even more monitoring.
It's the typical information/privacy land grab on information, that should be never used for such purposes, well certainly not retrospectively. You may have decided at the time, that the risk of getting a ticket was lower.
I wouldn't mind but most of us have enough to deal with trying to legally / stay out of bus lanes, keeping below speed limits 'today', when we are just trying to earn a crust.
I'm now wondering what methods they will be using retrospectively in 10 years time and modifying my ways accordingly.
