Cobblers. The number of cars, people and journeys has risen massively since East Dulwich was built, and even since the 70s when the idea you could just drive and park anywhere for free in London took off. That was always a dream, and it's dead. Even if your only desire in life was to provide enough free parking to meet demand, you'd have to copy Denver or Dallas and simply bulldoze half of East Dulwich to create more car parks.
