Well then where does the money for cycle route projects and the like come from? Because it doesn't come out of thin air.
It comes from a pot - which is made up of money - collected from taxes - of which road tax (or VED, call it Fred if you like) is a contributor.
This is where you should be focusing your argument. It's not that cyclists should be paying for the existing roads. It's that, possibly or at least arguably, they should be paying towards specialist cycling improvements to the roads; such as the superhighways in London, and this signalling change in Cambridge.
Why don't you focus your argument on that angle?



I think I've made my point absolutely clear and I don't see what else I can do.
