Back when I commuted by motorcycle, unless you were in the Hell's Angels, you waved to other motorcyclists as you passed going in the opposite direction. I thought that was a pretty cool show of camaraderie. When I started commuting by bicycle I hoped for something similar. So far, few cyclists wave and I feel like a nut bar when I do as they are usually not returned. Am I missing something? This is kind of weak. Especially since it seems we have even more reason to be supportive of one another than guys on bikes with gas powered engines.
