Lets get real..... it will not fall again... it will get progressively more expensive!
......and then when everyone is forced into the devil that is diesel, they will make diesel even more expensive to use
They already have. Diesel os already 4-6p more expensive than petrol and the fuel economy isn't that much better on modern diesels than petrols so it really makes very little difference whther you drive a petrol or diesel these days... the government isn't going to let you drive a car cheaply!
