There's plenty of Private Eye coverage as I previously stated if you're interested in their perspective in 'rotten boroughs' although it sounds as though you are a convinced enthusiast of LTN. Not sure if you bothered to listen to the part of the podcast about the claim (also a component of resident lawsuits

My original point is that my sister can no longer cycle and is dismayed to find it a lot harder to get around by car, while her son (a v strong cyclist) has to pay £15 congestion charge every time he uses his car as he lives on a band. He is convinced London has 'a war on cars'.
