The point is that at low speeds the wing does nothing, so it doesn't hurt to lower it, but at the same time, there is no point to lower it. So the motors and electronics that work to lower it are all for show, they have no function besides aethetics. And on the 911 shape, the wing REDUCES drag. The fast moving air coming down from the roof along those classic 911 lines produces BOTH lift and parasitic drag. So the wing does no wrong, it both decreases lift and decreases drag. I just wish they would come out with a tasteful spoiler and ditch the retractable silliness.
