I like to think of myself as generally well-adjusted, but I have real problems being passed by other bikes. Yesterday on a 10km ride to meet friends for dinner, I was moving along at a decent speed, and along the way passed a guy on an old road bike. He then picked up the pace and passed me in what I took to be a passive-aggresive protest at being passed by some gangly white guy on a single-speed folder with a helmet and blinkies. Neither of us made any eye contact -- for about 4-5 km, before I had to make a turn, we fought a silent duel with an uncertain goal. It was supremely silly, but there was some unspoken, underlying need to establish superiority.
How many of you can relate to this? Or am I less well-adjusted than I'd like to think?
