I get that that's what they intend to do, I just think they do a poor job of it.
My problem is that they all seem to assume your car is the size of an aircraft carrier. Cars are small, the air blows directly onto you in most cases (even when it's not blowing directly onto you, it's pretty close). SO if it's 70 in the car and i want it to be 68, the automatic controls will just blast cold air until the thermostat reads 68. Meanwhile I'm freezing because cold air is blowing directly onto me at max speed. It's easier for me to say "i'm a little warm, i'll turn the thermostat down one click and a pleasant temperature of air will be blowing on me" than "well, I want the car to be x degrees, am I willing to have 100% hot or 100% cold air blown on me while teh car tries to regulate?"
To each their own. I get that some people like to "set it and forget it."
