You're putting touch surfaces way too far for a normal driver to interact with. There's a reason why many of the automakers are using knobs/buttons by the resting position of the right arm to allow for interactions while in motion. My Mazda even disables the touchscreen while moving for this reason. With no proprioception on a touch surface you need to watch where your finger is going and that's a distraction. Not to mention gorilla arm fatigue.
