Back in 1996, I had a problem with sticky cleats and could not unclip in time. I fell over on my left side and fractured my left hip. I still have the three pins in my femoral neck. I now have platform pedals with strapless toeclips on all six bicycles. For the type of recreational riding that I now do, safety trumps efficiency. I get the occasional odd look when I show up for a club ride on my expensive bicycles, though.
