That is always weird. And the guy in the back sucks, can't hold a straight line.
Even when I am trying to set my land speed record, if someone approaches from behind, I keep my line and pace so they can pass safely. Can't figure out why these guys do this other than they suck.
If someone catches me from behind, I know I'm going to get passed. Let him pass safely so nobody gets hurt!
