There is no "road tax" in the UK, is it? It's a fee for polluting, not using the road. I hate that it's being used as an argument against cyclists: "get off the road, you don't pay road tax". This of course also ignores that most adult cyclists also own a car.. Norway have the same issues now. Almost all new cars are electric. You don't pay purchase tax / vat when buying it. Pay less on toll roads. Cheaper to use. Et…
Indeed, here in the states, cyclists pay for the roads that we use. For instance most local roads in cities and counties are paid for with property taxes. Income taxes cover a fair amount of road construction. The county bike paths have a fee. We're not allowed to ride on the Interstates, and we tend to avoid "big" roads for safety / comfort reasons.
My hunch is that if one were to look closely at the funding of roads, one would find that they represent a net subsidy for heavy trucking.
