One thing that might be cool, though not sure it would be cheap enough for the 3 -- charge ports at all 4 corners of the car. Would be nice to not bother trying to line up the charge port with the charger; just park however you like.
That would be expensive. Electrical plugs cost money.
My current car is one of the last cars that has the gas filler cap under the back license plate. It not only hide it from view when not in use, but I have never had to worry about lining up one side of the car or the other with the pump. Putting it in the back like my car isn't practical with modern trunk lids that come down to the bumper, but I think Nissan had the right idea putting the charge port in the middle front.
If Tesla did it, it would make using a supercharger easier. Backing up into a restricted space requires more ability to control the car than pulling in nose first.
Tesla could have put the charging port under a panel in the nose cone. They would have had to reroute things a bit, but the charger hardware could have been placed in front of the battery instead of under the back seat. It would make it a lot easier for people with poorer hand-eye coordination to use all superchargers. The idea of having to back into a space with $100K cars on both sides would be nerve wracking for a lot of people who are not that great at backing with precision.
