Metered electrical outlets for engine block heaters exist or existed, true. People driving around town dragging their plugs on the street because they forgot to unplug it did too, lol.
Actually they could be a government money maker think of every parking meter all the sudden becoming a parking meter / charging station.....
So your local city government becomes your electric / gas station for your car
crap you know that’s coming cuz they’re going to love that that’s a moneymaker for the city
so the government has a vested interest to double even triple dip
they give a big tax subsidy “paid for by you and me via gasoline tax” to have people buy these cars
And then the local government make profit on the back side and setting up parking meter/charging stations to charge these cars
And many electrical utilities are owned by the municipal government... so they’re the one actually selling you providing you the power end to end
