I’ve had my MX for a month now and had few opportunities on longer drives to utilize superchargers, but today I experienced all chargers full with 1 person waiting. I’m wondering the etiquette for waiting, because as I was waiting a 3rd person pulled up and began waiting. Is it like a gas pump were you pick a pump or two and wait for it to open or do you use the chargers in the order of arrival? I only ask after I was cut off when going to the super charger by car number 3. Also when I was leaving I noticed another vehicle waiting with its four way flashers on is this a standard practice also to show you’re waiting for a charger?
