Welcome to the peloton.
it would scare the crap out of me to try and ride in the peloton...
It's not as hectic as it looks. Most of the time it's a lot like dancing, everyone tends to keep their lines and move with one another. But it's much different story in the last 200 yards where fighting for lanes combined with lead out men trying to get out of the way as their sprinters go for the line leads to pure chaos.
