I see in older posts, and other websites, that whether your spoiler raises and lowers depends upon which car you got. The general trend was that only the P versions of the car got a spoiler that moves up and down. But Tesla's current page talks about the X generally, and states: "In addition, an active spoiler deploys from the rear liftgate to optimize highway efficiency and stability." It is not limited to the P100D or anything else. Can anyone tell me what is showing up on the 100D, as mine has not arrived yet. Sniff.
