It will feel a bit weird two or three times. But you will get used to it. I personally feel that there should be a selector so that the control remains in the hand of the driver. Despite that, you can just bring it back in Manual mode by tapping the lever.
You can feel the heat from the panoramic roof despite the shade cover which inturn effects the AC performance mildy but it is still sufficient. That even happens in e-tron GT having a seven layered glass, the heat presence in the cabin is still significant.
