Given that the damage to roads is linked to miles, and then the square of the vehicle's weight, it'd not be difficult for a state to stop putting the road maintenance related taxes on gas itself, and instead just measure those two things. Odometer change, times the square of the weight. Suddenly the really large truck that carries a single person is far more expensive to run than a sedan.
Something kind of like this is already done with stickers for electric cars in many states: Doing that for every car is just extending the program. It won't happen though, because a lot of people would be angry to internalize the cost of their choices
