Oh, I didn't mean to imply that people sending you videos intended to present the videos to you in support of an argument they were making or that the videos themselves were posted in support of an argument, rather that you thought they could be used to support your position in the OP : "I feel they are after seeing so many crashes on youtube."

Maybe you could share some videos.

One can run SPDs pretty darn loose. I can't imagine how they'd be more dangerous in a crash. Increased ground clearance over typical two-sided platforms and most single-sided platforms also, should theoretically prevent some crashes from pedal strike.
