They can only take up the entire roadway if you get intimidated and get off the road for them. There's no need to do that. They're not going to hit you.
Riiiiight...I should just trust them to not hit me when they're clearly piloting their bikes on the edge of their performance envelope (not to mention using both lanes).
Aside from that, i agree with you. But these weren't normal motorcyclists. I share the road with harley guys and normal sport bikes all the time. These guys were racing. Just "wave them by"? They're going too fast!
