I have to admit, I was pretty frustrated when I heard about this "rule" being enforced. 50% of my frustration was for those racers that were pulled and had to deal with the stress and drama, and 50% of it was because I'm one of those riders that toss the end caps from my grips in the trash. I think they're useless, and eventually fall out or fall apart anyway. Thanks to Huck for hooking me up with a set of plugs right before the start!
