Speaking as the guy above who flopped over while strapped into my not often used clipped platforms, let me say accidents can happen anytime, any equipment. I've slipped off unclipped/unstrapped platforms because of hitting a sharp bump and banged myself up. I've fallen over at a train crossing while helplessly clicked into clipless on my new, unfamiliar recumbent. I've never had any accidents caused by being snapped into my Look clipless. But maybe someday.....

Roesslk, the point DnvrFox and FarHorizon and I would all agree on is that being familiar with your gear is the key....friction or indexed, clips or not, STI or dt shifters...they all become instinctual after a while-- you don't have to think about it much-- you just do it. The more often you ride, the better you get.
