We've owned our 2019 M3-LR for a year and a half now and used the Tesla Supercharging network only a few times, and each time there were always plenty of open charging stalls. But as more and more Teslas are being produced, I've heard that Tesla Supercharging locations can get really crowded, and it's only going to get worse. My questions are: When you pull up to a Supercharger location with all of the stalls being used, is there a protocol for lining up to get your turn at the chargers? What if there is more than one direction from which to approach the charger stalls? Are there any signs posted to help people get in line to charge?
