Hi, does anyone feel annoyed that there's no scroll wheel on the AC vents to control individual air flow? All the cars I've driven had it and we were surprised to find that doesn't exist in the Tesla. My wife does not like the fan blowing at full speed at her. Also, how do you turn off the middle row center vent? I read that it's actually controlled by the Front climate control? Isn't that kind of stupid? My kids sitting in the middle row are getting too much cold air. Their feet are ice cold. Do I need to use duct tape?
