Well, ICE cars already are. I don’t know about Texas but certainly here in California there’s federal taxes on gasoline and state taxes. The state taxes are always explicitly paying for road maintenance, and the federal taxes pay for “infrastructure” in a vague but probably reasonable manner.

We’re all getting lost on the weeds on this one, but in general both the states and the feds are looking to make up the revenue needed to support road infrastructure lost when someone doesn’t buy gas.
