Conserving fuel is fine, and it was great in the past. The problem is that the drivers don't have to do it. It's all done electronically. You sit there, and it saves fuel for you, and that defeats the purpose.
With my father and uncle so involved in racing, it was the only thing I ever knew, so I'm sure that had a huge influence on me. However, my father had more influence on me just by the way he lived, because the way he was at the racetrack was the way he was in everyday life.
