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.
