At a guess I'd say there were 3 reasons for the increase in parked cars: 1. Mon-Sat There's probably 50% more active businesses on Lordship Lane than there were 3 years ago. Take someone like William Rose which employs 10 people during the week and 15 on a Saturday. Most of their employees have cars and obviously park them as near to their workplace as possible. 2. Increasing affluence of ED residents means more car owning households. 3. Increased popularity of LL means more cars especially on a Saturday from the affluent households living in surrounding suburbs (ie Herne Hill, Dulwich Village, Camberwell, Brixton). Now there's nothing we can do about the demographic shift and at the end of the day the increased number of car owning households is in line with the huge rise in ED homeowner's house values. But what a CPZ could do is dissuade those who could easily take a relatively short trip by public transport to either get to work or shop in LL but currently don't have the incentive to do so. I've never claimed that it's a fundamental right of mine to have a parking space outside my house, but is it so contentious to suggest that as one of numerous households with young children that we shouldn't have to spend 10 minutes pointlessly wasting petrol driving round and round the block just to get a space three streets away ?
