>Semis et al. definitely do not pay taxes proportionate with the damage they cause to the roads, but then again we all need them even if we don't drive.

I don't think there would be much point. At the end of the day we'd all pay it because we all consume the goods they deliver or transport during intermediary steps in the supply chain.

I guess you could argue that the status quo is somewhat of a tax incentive that favors local manufacturing (i.e they use the roads for every step of the chain vs imported goods which only use it for delivery). I don't take much issue with that.
