They will just move the tax to the Tesla Superchargers and the other electric charging stations. Alternatively they could tax it at the DMV level, like they already do to some extent. i.e. instead of a $100 registration fee every year, it will be a $500 registration fee.

I'm going to guess it will be a mix of both, but the govt(s) will be slow to do either, until they realize, too late, that they didn't meet their income goals on fuel taxes last year and suddenly have a shortfall in the budget :)

Applying a tax at EV charge points wouldn't work well because most charging happens at home. It's difficult to distinguish electricity used to charge an EV from that used elsewhere in the home.

I suspect most states/countries will eventually adopt a combination of higher annual registration fees and mileage-based road user charges.

Ah good point, make it based on usage.. your mileage counter says you went 100k miles this year, here is your 500k registration bill!

As for the charging @ home vs a supercharger(and the like) I agree with you, but the government is not known for always being wise or letting facts get in the way of something they want to do :) They understand a "Gas tax", so including EV chargers as part of the gas tax is easy to understand and easy to approve.
