When driving the other day I needed to adjust the climate controls and had to take my eye off the road for a second to see where they were on the center screen. It got me thinking about how I was able to control most things in the cabin by braille when I had physical controls. After driving a car for a while you get know the temperature control's shape and where it is with respect to other controls around it. With touch screen controls, you always need to get visual feedback to change a control. Of course with AP on you have more flexibility to do that sort of thing, but it is a minor annoyance. And you still have to look away when on manual control too.
