As much as I think I would be calm if I witnessed a crash, I am sure I would be freaking out trying to avoid bike parts, the bike and of course the rider. Glad to hear he was able to walk away. I get concern on some of my favorite roads that have metal guard rails lining the edge. If I went down, I am sure you collide with one of the posts supporting the metal rail. I am not worried about the sliding, just the "what you hit" to cause you to stop.
