Yeah, I don't know if I believe the claim that a "mode button is a standard UI for just about every car on the road today". My VW's have dials. My wife's BMW 528 (and I think all the loaner BMW's she's had: 3 series, X5, X3, Z3, Z4) have separate buttons to direct air at head and/or torso and/or feet. The buttons are identical, but one can identify them by their position: again, no need to look.

I hadn't thought, though, about his point that complete flexibility is likely to require a more complex distribution box. Does anyone know if the LEAF uses the sort of rotating single flap he describes?
The LEAF's ventilation duct
is of the "big box with a gazillion doors" variant:
