I'm currently at the supercharger in Barrie, ON with my Model X 90D. There's a Model S 90D charging here too. I'm wondering why this Model S is soooooooooooo friggin' loud while charging. My MX is silent. I walked passed the MS with my little dog and he got spooked. My car will be finished charging momentarily, otherwise I'd consider waiting for the MS owner to ask him about it. It just seems so strange to me. The MS is definitely off and I don't think it's his AC. It's not hot here at all. Any ideas?
