I've wondered about this one question for the better part of twenty years: why is there no option for you to set the air vent to split between face and defrost?
That is, the airflow options on (nearly?) every car I've ever driven are exactly the same: Defrost, Face, Feet, Face/Feet, Defrost/Feet. I appreciate that some newer models have half-points between some of these, but there has never been a face/defrost, which would seem to me to be the most appealing option, especially for those in a cold climate. (Defrost/Feet is the second best choice on a winter morning, clearly.)
Is it just on account of an arbitrary engineering decision that was made decades ago (perhaps to simplify some piping or electrics) and has just been perpetuated through inertia? Or is there an actual practical consideration why this does not exist? (I can understand how the vent system is not the most exciting feature to reengineer, but I would quite possibly buy a car with a face/defrost vent option.)
Or does this option exist even if I haven't ever run across it?
