Better Fuel Economy

Your father probably told you it's not a drag race once the light turns green, and he was correct. The winner in that race loses gasoline, and perhaps more. But this is not a safety lecture, it's an observation that punching the accelerator damages your mileage like few other bad driving habits. On limited access highways, use that acceleration lane to its fullest length, gradually adding miles per hour until you merge at a speed comparable to the existing traffic. Gradual, even acceleration is a fine art for good drivers, and practice pays off in better fuel efficiency.
