With the continued shift to EVs, petrol taxes just don't make sense as a form of taxation to pay for roads. I think we should be shifting entirely to a gross curb weight tax for all vehicles. The fourth power law states that the greater the axle load of a vehicle, the stress on the road caused by the motor vehicle increases in proportion to the fourth power of the axle load. Meaning heavier EVs cough hummer, are doing x^4 damage over my already heavy car.
Capturing vehicle taxes by weight should incentivize lighter vehicles, and therefore, less tire wear.
