Having had our Model S for 20 months, and with an X reservation, I would like to submit to tesla a request to move the A/C controls from the bottom to the top of the screen. If one needs to adjust the A/C or Heating controls when driving, it requires that you look way down from the road to the bottom of the screen to make changes. In older cars with a rotary knob, you could do this by "feel", but with the touch controls you have to actually look at them. And, with them at the bottom of the screen, it requires that you move your eyes far away from driving to locate where to tap. Having them at the top would seem to be safer.
