So basically pedestrianise the centre of London
Now that's got my vote. Londoners don't need a car any more because you can't get anywhere, and if you did get to your destination, there's no where to park!
Everyone starts walking or riding a bike. People get fitter, NHS saves a fortune in diabetes treatment, Council stops digging the road up, air quality gets better and Londoners finally start smiling
If you want to leave London, get on the train or Johns Coach
