Since this thread has started to revolve around climate control, I would have to point out that my favorite automatic climate control system I've ever used was also the very first one I ever saw- in my wife's old 1993 Chrysler LH car. The algorithms they used to compensate for solar loading (via a sun sensor on the dash) to skew the actual air temperature (sensed by a thermistor out of direct light) and move air flow between floor, dash, and defrost worked much better than most of the ones I've had since, including other Chrysler systems. On that old car, when the sun came out from behind a cloud the fan would speed up a tick or the air would bias more toward the dash vents so that my skin wouldn't feel so much hotter. Almost all the time I could punch the "auto" button, set the temp, and that system would do the right thing without me messing with it.
Many of the newer ones do OK in winter, but in the summer they just won't run the fan fast enough to offset the sun shining on me, or won't switch out of bi-level to move more air across passengers' arms and faces. And the old LH system had BUTTONS and KNOBS. One button for full auto and a knob for temp, and then adjusting any other function (ie. fan speed, air directed to dash, floor, or defroster) would take that ONE function out of auto mode but leave everything else automated. So if you were comfy but your feet needed more air, you could just push the bi-level button and the fan speed and temp would hold the same, but the air flow wouldn't be re-directed based on temperature or sunlight anymore. I loved that system. Loved the whole vehicle, actually, but at 250k miles we'd gotten everything out of it that really made sense.
