It seems to me that what Tesla really need (and I'm amazed they have not done this) is for the cars to automatically negotiate queueing at busy superchargers. Right now, its all pretty much physically get in line (if there is an obvious way to do that) or try to figure out who comes next based on who was parked someplace close to the SC before you arrive. Why can't the cars do this? And tell you in the app when your "number" is coming up so you can get coffee etc while you wait your turn? And how long your wait time is (approx)? The cars already know they are going to charge, and that they are close to the SC, and they can all communicate with the mothership to coordinate the queue.
