Re: cycles and tax
Well said, sir!
We don't have hypothecation of taxes in the UK*, and for very good reasons too, hence paying VED on one's car(s) has nothing to do with maintenance of roads.
A simple example: if we had hypothecation (or ringfencing) of taxes then childless people would be asking for tax breaks on the basis that their family doesn't use schools. Similarly, the healthy would be demanding tax breaks on the basis that they don't use the NHS. Taxes on cigarettes and booze don't go to NHS directly, they go into a central pot, just like motoring taxes.
The local roads, on which people will find people riding bikes, are built and maintained by local authorities. Who pays for them? All council tax payers do. Of course, the extension of the logic that has been on display by some of the trolls, students and other persons who don't pay council tax should not be allowed on pavements, roads or anywhere public.
DfT has made it clear that it will not bring in any form of cycling tax as they would have to tax pedestrians too.
