So you are wasting all that gas just to stay a little cooler. Now it can be modified. In other words if you are going down the freeway at 70, I will roll up the windows because then the Coefficient of Drag is so great at 70 that it makes a difference. But if you are in stop and go traffic in the city or going up hills, shut that air conditioner off, roll down the windows, you will save a ton of gas.
