IMO the real sin there is the defogging, because that can arise when the driver needs immediate results and is already distracted by difficulty seeing or bad weather conditions. I'd prefer it be part of a row of "panic buttons" along with the hazard-lights and "all wipers to max." In contrast, stuff like "airflow toward torso" versus "airflow towards feed" or "both" is stuff where you can either wait to feel it or else glance at the settings during a safer moment. This assumes, of course, they don't do something stupid like have the "current setting" vanish from the screen on a short timer...
