Here's a very cool video on how much benefit you get from drafting in cycling:
This really helps explain why riders on a break try so hard to get others to come with them. The most interesting part of the video, though, is how the rider still benefits even when someone is drafting off him. The drafting rider smooths the airflow, creating less turbulence and therefore less drag on the lead rider!
