Ordinary taxation is already a major source of funding for road maintenance and of course the massive externalities. Fuel tax in most states is a flat rate that hence isn't automatically adjusted with inflation, and it's political suicide to increase it (just love that cheap gas, but tax those EV fuckers, they are not paying road tax!). It's pretty much a laughably low amount by now.
