No laughing matter when a truck driver and bikers are seen bumble beeing all over the road, speeding, manhandling each other to make a speeding point.  Anyone of the front bikers could've been in a horrific accident or killed.  Nobody, especially bikers, don't have special road rights.  I oftentimes see bikers rocketing all over the highway just to get nowhere fast.  If you can't drive safe get the heck off the highway and stay off.
