The truth is that we do pay for roads and at a level that is commensurate with the amount of wear we are responsible for.
Gas and use taxes do not cover the cost of building and maintaining highways. I posted a link earlier that shows how much of each state's use fees/fuel taxes cover. In total it's about 50%. Much of the other 50% comes from the general fund that my income taxes go to. County and local roads are funded heavily through property taxes and ad valorem taxes.
And I just posted how my state funds it's roads, including county and city. No where NEAR 50% is from the general fund.
And how much of the road funds are diverted off for bike paths? In the metro area it's 12% of the road budget. How much do bicyclist's fees and taxes pay for that? Zero.

Looking at the funding it looks like right around 70% of the state's county's road funds come from vehicular taxes and fees.
Well, that leaves 30% which is a far cry from the "zero" figure you used.
I said that bicycle taxes and fees paid for zero of the bike paths.
