Because that doesn't get nearly close enough to the cost of roads. Interstates alone have, I believe, cost us over 25 trillion. Just interstates, not all highways.

That number seems very unlikely to be accurate. It's more than 2x larger than all local, state, and federal government spending in 2025 combined.

No that's the actual figure since the 60s when they were built. I'm cheating a little, that's not a per year number.

It works well in many (most I know) countries: is fuel+license more common than general (income and fuel and other) taxation ('normally' would imply most do like you say?).

If you use income taxes, then people who drive less are subsidizing people who drive more. It's bad incentives.

But that does not make it 'normally'; where does it work that way vs income(and other) taxes? Where I live and all countries around, roads are paid from general taxes (including income, road and fuel taxes).

Well ice cars are going to be declining in market share so we will need to implement an electric car tax to offset the cost.
