They can mandate separate metering for the charging circuit and tax it to make u p for the lost gasoline taxes.
And can always charge L1 120v, even if it's unbearably slow.
Or, they can just tax the car based on some average mileage statistics. That's what my state does. Registering an EV is substantially more expensive than an ICE vehicle.
Only if you trade in a gasoline SUV for an electric SUV. A hatchback EV weighs about as much as a compact SUV, and is cheaper to buy and operate.
Because trucks also used more gas. EVs don't.
