Don't know if this is possible, but I figure since our phone's Tesla app is linked to the car, would it be possible to contact another MS owner's phone at an occupied supercharger station once the other person's charge is complete, so they can return & move their vehicle for the next MS? Maybe we can enter the occupying MS's VIN or license plate number that allows us to send a message through the app to that owner's phone? And it would just be a software update if that's possible.
