teaching my girlfriend about the draft you pick up on the highway, like nascrap has. i was goin like 75, then snuck in behind a 18 wheeler, now my mazda isn't so stable and smooth and fast going 75, but behind the 18 wheeler i had mad acceleartion, she didn't understand why my car was so much smoother. i wonder if my car could hit 150 if i was behind a truck like that. it was kick ass.
