"Road TAX" is basically a tax on emissions, which is why some cars pay £0 a year. (Nerdy fact alert!): Road tax was abolished by Winston Churchill in 1937. This is the same argument cyclists have when people shout at them about not paying to be on the road, technically neither are motorists, they just pay to pollute it. The main issue I have with VEL is that we never see where our yearly payment goes. As it is swallowed up by other government spending. General taxation pays for the upkeep of roads, hence why our local councils don't repair roads, if they were getting a percentage of "road tax" they wouldn't have an issue.
For info, on my 57 plate 350Z I paid £435, a 2011 plate GTR I see on a daily basis near work pays the same .
