Any CPZ will only push parking problems to other neighbouring roads. Account needs to be taken of this effect if any CPZ are to be created.

And what happens when council funds are a little low? Extra charges for CPZs. Lewisham is still fairly cheap, but don't count on it staying that way. Here's a petition in Barnet against excessive CPZ and other parking charges http://www.gopetition.com/petition/41889.html
