Ouch. That sucks. Hope your friend heals up and feels better soon. It's scary to see someone get hurt like that.
I've always been hesitant to get into cycling because of my own nightmares of this happening. I'm usually near the back of the group because I feel I have more control going slower. With running if you fall, you might scrape up hands or knees, but with cycling you can really end up battered.
That is true. Everyone has a different risk tolerance. Personally, the fun I get from riding outweighs the scary factory - unless I'm going down steep hills. That, to me, is pretty frightening. I still do it, but eeek.
