To be fair, H-bear, if the rider and his friends pulled over (I'm assuming he means stopped and off of the road) to let the racers go by, then he isn't one of the riders that the OP is talking about.
I'll tell you what, though. I live not too far from the event and have contemplated doing it next year. After reading all these posts (this one as well as many others), it sounds like a nightmare. I guess I'll just have to ride 100 miles by myself.
