Do California Tesla owners care enough about carbon footprint to use the self parking summon feature to home charge the vehicle with a better efficiency than what is provided by the hand engaged plug used today? The home charging scenario is an ultra efficient inductive charge port under the rear bumper, near where a dual exhaust pipe on an ICE is today, except further under the car and even less visible. The vision is an electric toothbrush like paired "pin in hole" (close coupled) inductive charger with half the carbon footprint of the latest beautiful non-contact inductive chargers. [Pretty sure it can be made more efficient than the plug in charger that is used on Tesla's today, too. The expectation is 'rounds to 97%' efficient from the wall to the battery bus.] Charge rate would be 7.2 kW. Would not work if you come home to half an inch of black ice, so this would be a regional, warm weather, or covered parking option.
