IB4ButIsawitonmythbusters
I only run my AC when absolutely necessary (eg. Females in my car)
haha I saw that mythbusters too. except i believe they tested it on a suv of some kind and of course windows down won but to me having the a/c on didn't make much of a difference since a truck gets bad mileage anyway. in light of that, i wish they would have done it on a car.
i also only use it when my girlfriend is in the car, or if i'm going somewhere where i can't arrive all sweaty and panting.
