Can’t we just learn by reverse engineering? From the outside, that seems simple enough; watch better riders and just copy what they do. Unfortunately, when watching other, better riders, you can’t even see, much less mimic, the subtle perceptions that initiate the actions required to ride well. Forcing someone into Marc Marquez’s riding position is tough enough. Then there are those outrageous, elbow-dragging corner antics, which are contrary to our very survival instincts and patterns. Short of a Vulcan mind meld, learning by copying someone like Marquez isn’t going to work for most of us. Golf swings, batting, skating, diving, swimming, hurdles, and more athletic pursuits suffer the same problem. How do you accurately and simply describe and communicate such a complex action?
