I am impressed with a number of things: that is terrific quality for the cam. I'd like to know what brand it is as well. I want one. You sure manage to keep reasonable pace with the cars as well, very nice riding. The route looks pleasant enough but that tunnel looks scary and the narrow shoulders are almost as bad.
I agree with the observations above: that right lane with has had the surface removed looks treacherous nyet you handled it very well. I could feel the jarring vibrations all the way over here though.
