> The roads are paid for in a large part by road taxes and fuel taxes. Cyclists pay zero towards it in direct taxation, apart from general taxation that everyone pays anyway. Why should cyclists be able to free load off of infrastructure paid for by tax-paying vehicles, and dictate that they are built to favour cyclists when they are not contributing a single penny?

The bulk of road funding is from general taxation in most places (including the UK, I think?). To put a bit of a spin on your argument, most tax is paid by urban areas, with rural areas generally being a funds sink. So, should rural areas really get roads at all?

See how silly that is?
