Interesting guys. Thanks for the answers. I often see motorcyclists with their left arms kind of resting on their thighs or on their hips. It's not like these folks are holding beers or posting to Crossfireforum.org (lol) or behaving in an unsafe manner. It just appears to me almost as if they are "cradling" their left arms/hands and treating them rather gingerly. Kind of like favoring a leg if you sprained an ankle. I thought maybe there was something about the "clutch hand" that was special.
