Perhaps, now I'am just saying perhaps. It seems to me that our best drivers have an element of athleticism. Some drivers are very smooth, almost gracefull(if you will) in the way they perform their duties. From putting on a seat belt while turning the ignition key, stopping the vehicle, opening the bulk head door, then selecting correct package(s). It's one whole smooth action. Most played some kind of sports in high school or even college, thus they bring these skills to driving. Even some of the chubby guys can be athletic. I, could be wrong.
