I am an experienced motorcyclist, and I got passed in the Swiss Alps (down hill of course), by a bicycle. That was the ultimate humiliation to me. I was watching this guy pass everybody coming down that pass (tour buses, cars, other motorcycles, the guy was flying), and by god, he was NOT GOING TO PASS ME! So I wicked it up, and wicked it up some more. Finally I waved him by, no way could I keep up that pace....
