Yes sir.... IMO People wreck....If some people push harder where you are in a group, there is more of a chance to be a crash, just because they are pushing oustide of their limits. Just like riders push harder and harder while they are running on the track. Wrecks will happen.... I feel that if you are in a group and you ride outside your limits that day....your chances for a wreck is greater....but we are all adults(somethimes)... Ride the way you are most confortable and in control.... Dont ride to try impress... When you are in large groups, people need to remember one wrong decision could hurt all of people...and not just yourself...
