That wasn't the question. What is your experience in this situation to think you can pass judgment? I may not agree with everything Erik says in the Youtube comments, but at least he has the experience to back up his mouth. You have zip. So zip it.
Clearly you were not paying attention or you would have seen the group approaching the rider. Sorry if you can't accept reality. If I agree with the pro, then I guess I am correct to share his opinion if indeed it is my honest opinion. I can tell by your comments on youtube that you are clearly the crybaby denying responsibility.
If you're asking have I ever rode in big groups doing 30, yes. That's where I learned that it aint too smart an idea to ride blind whatever the speed, whether it was a crit training practice with Incycle or a mid level racer like yourself doing a 40 mph sprint for nothing on a training ride just to get video to impress a group of riders on the forums with your superduper wattage that also means nothing in the realworld like my fun ride videos!
