You're in the 'Dark Ages' as far as apportionment is concerned. Pre-1992, interstate trucking had what we called 'Bingo Plates' that were affixed to the front bumpers of each tractor. Trucking companies had well staffed- and paid- personnel to tally up how many miles each truck pulled a loaded trailer across the various states. Then they had to send funds to some states, and bills for additional road-use-taxes levied, that would be divided up among the states.
That all ended with the 'Surface Transportation Act of 1991'. Now, there is a large percentage of road-use tax that goes to the Federal Gov't, and some states charge a smaller amount to cover state highways and general road construction and maintenance.
What you're calling for turns the calendar back over 30 years. Owners of EVs pay a premium on their annual registration for road upkeep, and excise taxes paid on tires is higher on sizes used by heavier vehicles.
The loser is the sticker-printers, who lose business and contribute zilch to solving the issue.
Carolinian, when you choose an issue to push back several decades, please research the related history.
