I was out on a leisurely ride today, and ended up crossing paths with a few cyclists. There was one instance where I said "how's it going" and all he said was "get out of the way". I wasn't in his way at all. Completely unfriendly and rude!
I realize that there are times where you'll come across cyclists like this, but maybe they're the reason why drivers have such a bad stereotype about cyclists.
I don't know, just a thought.
