An odd set of examples to prove a point. When I got back into cycling 15 years ago, I stayed away from clipless and used the old fashion clips and straps. I finally gave in 5 years ago and never looked back, though I must admit, I got at least a couple of months using them on a spinning bike before I took the plunge and put them on my hybrid.

I have fallen, maybe once or twice with clipless, but I also fell a couple of times with clips and straps. In general, it is far easier to dismount from clipless than it is from clips and straps.
