When I was learning my advanced motorcycle skills my instructor said the only way to know when you are on the the limit is to pass it. It’s why in practice in all sports you see them seemingly make mistakes, miss, wobble or crash. The fact is they simply need to find the very edge as that’s where the fear lies and the opportunity. If you won’t go to the edge someone else will. I’d prefer to wobble rather than crash but if the edge is the place to be then so be it.
PS I thought about this as I was riding my motorcycle last week and tried a new line through a roundabout and lost the front for a microsecond before regaining control.
