I am trying to figure out (based on a thread over at the Tesla forums) what ESC is. It's listed as a separate item from Traction Control on the Tesla Model X specifications page. Yet in the Owner's Manual, the entry for Stability Control in the index takes you to the page for Traction Control. So... is there a separate stability control, and what does it exactly do? My other thought is that maybe they mean how the air suspension will try to keep the car level.
