Maybe lessons can be applied from very small groups of cyclists, but if you ever watch professional cycling races on TV, you will notice that almost every big race has multiple mass crashes with several people on the ground, often with injuries that take them out of the race, and the bulk of the pack delayed trying get through the mayhem.<p>Many of the crashes happen simply as a result of every racer trying simultaneously and impossibly to be near the front of the pack before the finish or before some other important part of the race. People in large groups tend to be dumb. Maybe there is a lesson in that.
