For instance, if I start up with auto on, and it thinks the fan speed
should be 100%, and I manually kick it down to 50%, then it will keep that
"change" (i.e., I want it to have a fan speed equal to half of what it
thinks it should be). So later during the drive, when the auto wants the
fan speed to be 70%, it'll make it 35% (since I want it to be half of
that). Very cool. Now that winter's approaching, I've also noticed it
keeps a low fan speed (in auto) when cold started, until the engine is
warm (so it doesn't blow cold air at you).
Of course, I *am* a computer programmer, so maybe I'm just imagining that
there's a cool algorithm behind it all :)
