Way too much trouble for the little benefit of getting into a cooled down car in my book.
Here in SoCal we can get high 90s almost year round and I never needed the pre-cool feature yet.
Open door, start engine, open all windows and start AC....start driving...Close windows as desired....
But then again being from Germany I love the warm air and the sunshine ;-) So most of the time I have the AC off and just roll the windows down.
I usually ask to sit on the patio in restaurants as well rather than in the freezer cold most people seem to prefer around here :-)
