Its become fashionable for the anti-motor lobby to say that the additional money paid to the government for a tax disk does not pay for roads, that roads are paid for out of general taxation. that the tax paid for your tax disk is to pay for the emissions of your vehicle.
1) People who tax their cars do so because they want to use roads. If they don't want to use roads they would not have a car and would not tax it.
2) Road Tax is not based on the emissions of your car - it is the same whether you run your car 24/7 creating maximum emissions or never run your car creating zero emissions.
3) Even the bike-nuts say that Vehicle Excise Duty (which they say is not a tax) goes into the central pot of 'general taxation'. How can anything that is not a tax go into the governments 'general taxation' pot? It can't - this bike-nut claim is nuts.
So in summary, car owners pay road-tax/VED because they want access to roads, that money is taken by the government in a pot which is used to pay for roads.
What morons gave Kaya Burgess an award for coming up with his crap? Sheesh.
