That seems like an implementation of the 'mass surveillance' solution to distribution. That probably appeals to many politicians, but to me that is intolerable.
It would also require different governments to cooperate; New York would have to be able and willing to redistribute part of my milage tax to a foreign country when that country says my car has been there. I don't know if that's feasible, but cynically I assume it would be difficult at best to put into practice.
You know that's already happening right? For example, SunPass in FL will bill you by your license plate as you go through automatic readers, and mail you a bill to California if that is where your car is registered.
The 'mass' in 'mass surveillance' is a matter of degree. Most roads are not presently toll roads. Most are not presently tracking all cars that drive on them.
I don't find 'some surveillance happens already, so we may as well go all in' a compelling argument.
Mass surveillance is about indiscriminate surveillance(recording everyone that comes through in case a bad guy comes through), as opposed to specific surveillance(trailing a mobster to see where he goes). You can have mass surveillance on some roadways without most roads being surveilled.
You can have mass surveillance at a stadium and no surveillance outside the stadium. Likewise, you can have mass surveillance on a toll road and not on county roads.
Part of your point was the difficulty of inter-state cooperation in this regard, which is incorrect, or at least the difficulty has already been overcome, because this data has been shared with SunPass for ~20 years.
And no one made an argument that because we have a little we should have a lot. My point was that what you find intolerable of is already happening.
