I don't like thermal shocks when getting in/out of the car so I stick it to a low-ish temperature in winter and something high-ish but still bearable in summer.

I really don't like getting out of a car cooled to 18 C when outside it's 30+.

However this just proves "smart" automatic a/c is useless because, newsflash, different people have different habits.
