Surely climate controls change far more based on the weather at the current moment than on the preference of the individual drivers? My wife and I have polar opposite preferences for cabin temperature and airflow, but even if the car remembered our preferred settings we would both be changing them frequently anyway.

I would much rather retain the ability to quickly change temp or re-orient a blower without taking my eyes off the road than for the car to remember that I like it cool and breezy and she likes it like a furnace.
