There was a time when the radio in your car had a dial and some push button slides. It was also mounted very low in the car. You certainly had to look down to adjust the radio, at least to see where you were starting at. Heaters being the same thing. Look away from the road for a second in order to adjust the settings. I still don't like the heater in my truck today because of it's location. OK, we made it through those days, because we had the brainpower to realize we were momentarily distracting ourselves from the task of driving.
