I think it's pretty clear what he meant. I missed whether or not he or anyone has a problem with the "drugstore racer"... but I will say, it IS a blast dropping them on the bike path. Kinda dickish, I know, but, like passing guys on TTs, it's a blast. I blame my cycling partner for instilling the desire to embarrass them, when I'm normally not that competitive at all.
EDIT (because you wrote me back)-I don't know what makes them behave that way or whatever. I do know that some people probably get in some fantasy mode.
