Despite fuel duty increases, the real cost of motoring fell by 14% from 1980 to 2010. During the same period rail and bus travel increased in price by 60%!
Private car use is a major source of carbon pollution, causing climate change and health problems.
An increase in fuel duty by 20p per litre would give Government £8.5bn income.
