I listened to this podcast earlier today, very interesting. They interview a researcher at University of Utah who studies distracted driving. The ergonomics and related distraction factors of In-vehicle Information Systems (IVIS) are fascinating from a UI perspective.
Unsurprisingly, tactile/physical controls are much less distracting than voice controls or virtual controls like touchscreens. Part of the reason is because physical controls are faster and more precise to modulate, so your brain is distracted for less time while doing something like adjusting the temperature with a physical knob.
