Personally, I don't care at all. I let it do what it wants, if it doesn't work correctly, than I fix it. It doesn't bother me, it has no impact on how I drive, it isn't really noticeable. The gas savings from not running it would be negligible. Besides, cars get far worse fuel economy during colder months anyway. If you were trying to race someone, then it might matter.
I love cake. I AM THE CAKE BOSS!
