I see a bigger issue here and that is lack of Cycling courtesy. Certainly in years past there were fewer of us out on the road (how many of us have ridden across the road to greet a cyclist?time frame was long ago when lightweight bikes were really rare) Modern Cyclists hardly ever respond to the nod of the head or wave anymore. I belong to a team with national scope as well as a local group and find even my fellow ''brothers'' dont take the time to wave. I understand if you are on a fast downhill or passing a huge group going in the opposite direction its one thing. In years past it was common to point out bad dogs or detours or rough road ahead. Today it seems they are to intent on their own thoughts or technical accoutrement's.
