> This is why I advocate for a gross vehicle weight rating and vehicle miles traveled tax

The problem is, while that works out on highways and other federally owned road, the distribution on state or county/city level is almost impossible. Say you have a trucking company doing regional service and one doing interstate transport - both their fleets will have similar driven miles because economically, companies want their many-hundred-thousand-dollar assets to be on the road as long as traffic safety laws allow. Now, assuming they both pay the same mile tax to the state... the state makes an insane profit on the interstate trucking company given that only a low percentage of the miles driven were happening on that state's roads, with the clear majority being on federal highways and other states' roads.
