jasongilbert,
You did make several conclusions and comments, which is fine except for the claim of not making any.

I do take exception with the conclusion that at least one of the cyclist had to be “clipping along” for such a serious injury. That injury can occur from simply going over the bars or simply falling off the bike and speed is not a requirement. The height of the fall is.

I watched 2 cyclist collide head on, they saw each other and one had slowed to < 3 mph and the other stopped. The one still moving caught her front wheel on the other bike, it turned 90degrees and she endoed over the bar onto the back of her head. She had breeding from the head and a hard time not passing out. One of my EMTs was also riding the area and so the cyclist got immediate medical care.
