I don't think many people disagree that we all need a lot less car journeys in our cities (more difficult in the countryside). So what we need is more buses and things like Boris bikes. Then disabled and old people should be able to drive if they have got a proper blue sticker showing they can't use buses and tradespeople get permits to drive. the rest of us get off our arses and use public transport. if they can do it in Scandanavia then we can do it, right? Not sure why its taken 63 pages of comments to get to that answer - I knew I was right :-)
