Finer Temperature Control

It seems like whenever I am driving I need to play a ridiculous game of balancing the AC blower strength and the AC temperature control in order to get the climate in the car just the way I like. If I don''t fiddle with the knobs I either get too stuffy or too cold. The problem is that there are such large differences between each setting on the AC.

Now I will admit that it may be possible that some luxury cars implement the suggestion that I am about to make. I would not know. I do not drive those types of cars.

The thing is, thermistors (electronics that are sensitive to temperature) are not that expensive. It wouldn't be pricey to allow the driver to punch (or dial) in a specific temperature. If the ambient temperature is colder, the car turns off the AC (and possibly turns on the heat). If the temperature is warmer however the car kicks up the AC to optimal level to hit the target.

"But Richard," you might say, "What if the blower is a step motor that can only operate at specific levels." To that I reply there is an easy solution that is still cheap. A bypass vent connected to a servo. If you want to reduce the air from the blower simply redirect some of it elsewhere.

Ultimately I believe that either
1) This actually exists in luxury cars and I just need to drive a higher class of vehicle.
2) This is a good idea and has little barriers to limitation
3) I am simply too picky

Have comments about my ideas? If you see something wrong with them, leave a comment. I'll try to comment back. If you have seen these ideas implemented/mentioned somewhere before, leave a comment. I like to think I am 'original' but that doesn't mean somebody has not beaten me to the punch. Finally, if you just have something to say, well comment that as well.
