either way, we're splitting hairs here. modifying your driving one way or the other would probably result in near immeasurable differences in fuel consumption.
wanna save fuel? drive with your top up, inflate your tires to 36psi, go slow on the freeway, and accelerate at a boring rate. me? i bought a porsche precisely because i don't like to do ANY of those things (except keep the tire pressures proper)
