While touring scenic route 63 the other day, a group of V-twinners was leading a very lengthy convoy of passenger vehicles and one trailer truck, at a brisk 34 MPH in a 50.
I yelled out "WTF is your problem?" at least three times in 5 miles, but at 700 feet away, I don't think they heard me.
3rd gear red line
4th gear red line
Problem solved
I wonder if any of their heads spun around from my draft wind, like in the cartoons? Hope so...
