I’m flying out tomorrow to go purchase a new to me car from a dealer about 11 hours away. We currently own a MS so am familiar with adding a car to my account. It says on Teslas web site that it can take 2-3 days to add the vehicle to my account after the appropriate documentation is provided . My question is how can I use the supercharges for the road trip back when the car is obviously going to say that supercharging is unavailable on the screen? Thanks for the help. Marc
