I can see a case in limited circumstances. But my road is not heavily parked and there is no justification whatever for taking £120 or whatever amount off me and everyone else there per year for a system which will probably - granted, not certainly - but cumbersome to administer and live with.
And I totally agree with the thin end of the wedge point - the experience in Catford shows that once introduced, the prices and complications go one way - up - and at one speed - fast.
