I took possession of my M3 AWD on New Years Eve. I've use my in-home charger since then, but it's time to travel and use superchargers. Dumb question: how do I open a supercharger account? I can't find any mention of it on the app or my Tesla account. I'd hate to be far from home and realize that I can't use a supercharger. My account is associated with a credit card; do chargers automatically ID your account by VIN and charge you? Thanks.
