Shifting tax from a vehicle licence (road tax) onto petrol only penalises those who use petrol lawnmowers, chainsaws, race bikes, generators and lots of other petrol driven machine which don't actually take up space on the road.

Personally I'd be a lot better off if we switched to pay-per-mile, but I know that a lot of other people - self employed particularly - would really suffer and either be forced out of work or put up their prices. So in the long run you'd end up paying for it all anyway.

One can only assume that, as with the congestion charge, MPs would be exempt...
