I do feel very lucky--so far-- on the road bike. The common form of clipless fall is that you unclip left foot and then over balance right. Nothing you can do about it- it happens and when you least expect it. I have done the unclip left and then start to fall right but Mountain biking taught me to trackstand. I have no idea why I have not fallen but perhaps it has always been in a secluded spot away from any spectators- or there have not been any off-duty nurses about.
