> Physical buttons cleanly resolve all of these major problems. It depends on how the physical button works. You functionally don't get tactile feedback if the response time isn't good. You don't actually always know that you've activated a control (e.g. Did I not press it hard enough? Did I need to rotate it further?) Cheap buttons or knobs or dials can often feel mushy and be unclear as to whether you've fully turned them or pushed them. Not taking eyes off the road is definitely better, but general distraction is still a problem even if you don't have to look away.
