Freezing Fuel Duty is Wrong

Yesterday evening, fuelled by some excellent real ale (only 3 pints), I rang 5Live to tell Tony Livesey that I would be happy to pay an extra 3p a litre for my fuel. My point, which is difficult to make in a sound bite on late night radio, is that the price incentives are wrong. People need to be incentivised to use their cars less, to drive smaller cars and to drive more fuel efficient cars. Car manufacturers need to be incentivised to produce those more fuel efficient cars and find alternatives to the internal combustion engine using precious oil and creating pollution. I also suggested that the real cost of motoring has risen less that the real cost of using buses or trains. This would make a good discussion point with classes. I need to find some data on the cost per passenger mile for cars, buses and trains. Any help here appreciated.
