I have a teammate who is very, very strong, but not very comfortable in a pack. He comes from a Tri background. As a result, his MO has been to just ride away from the field. So far, he has done it in every race, though I suspect that might become more difficult when he cats up to a 2 later this year.
As for the original post, every race seems to have some sketchy riders in them. It's to be expected. To encourage people not to race because of that is just stupid.
