As ever, it's going to be a transition. I hung on to a petrol car long after diesel was the cheaper option. I was getting hammered for road fund and fuel at 38 mpg. But I persisted, because I'm bloody minded like that. I now run a diesel, it's great and dirt cheap, but congestion charge s are coming. To me? Not yet, but one day. It's already happened in London, and Edinburgh, Glasgow, Perth (or is it Dundee?) Have followed. Bradford has it for vans. It's not going to change overnight and the rural areas will be the last to have congestion or eml ssions charges and the last to have chargers on every street corner. It's coming. Some places sooner, some later. Some people sooner, some later. Early adopter s will pay, the trailing edge will also pay. The rest of us will change when it's the most sensible choice.
