Apparently, this guy does not live in the south since he suggest not using the A/C at all. Yes, I really want to jump into my Galaxy Black Titan with leather seats parked outside all day on a 100 degree day and not use the A/C at all. However, most ot the other ideas are still doable in the south. I wonder if anyone has tried the hypermiler contest with a truck pulling 10k lbs.?
