Uh Yeah, Stop and Make sure your straight.... Once everyone quits laughing at his/her ass I might even call a wrecker. Assuming the hammerhead isn't hurt. I mean even if they were screwing around, injured isn't funny...Well OK seriously injured ain't funny... Broken ankles are funny....I HATE when people stunt from the back of the pack. Because almost every year some assclown loses it and not only takes themself out they take out an unsuspecting rider from behind.
Hint: If you want to stunt, do it in front of every one. So if you bust your ass. We can all stop in time and make sure your straight!
The blind spot thing and learning how to ride in a proper stagger are good points. I do get tired of trying to F'ning explain the concept of your in the left, I am in the right, make sure you can see my eyes in my mirror. Oh and stay back far enough so I can swerve if neccessary in my lane.
Oh and yeah, single file in the twisties folks.
