I've found that the majority of functions needed when driving are available through the steering column's stalks, left/right buttons, or voice commands. If I ever do need to use the touch screen, I can activate TACC & Autosteer, and glance back and forth between the screen and road while finding the next button to press. And for the common functions, I've developed an awareness of the button locations, so I can press them while maintaining a view of the road. Sort of like how I had a sense for the physical buttons of my last car; only difference is that now the sequence of button pushes must also be learned, not just the physical location.
