I'll start this thread, because I had a "rude cyclist" experience this morning on my ride.
I went out about 7:45 AM, just to do my usual loop and maybe add on a little more. I decided to do the loop in the direction so I would not be in the morning traffic. As soon as I got on one of the main roads (Lowell Rd), someone came up behind me and said "on your left." I think I had slowed a bit, and was going maybe 14-15. I was hot, had my vest and arm warmers on, but I didn't want to stop after like 3 miles. So, the person passed me, but she really wasn't going any faster than I go on a good day. She was young, was clipped in, had cycling clothes on, but had a sweatshirt tied around her waist, which to me is a sign someone doesn't know about things like arms warmers or vests that can be stuck in a jersey pocket. She didn't have gloves on, either. I didn't want to pass her, as I knew I couldn't maintain a speed faster than she was going for more than a few minutes. So I asked her, "Do you mind if I stay behind you?" I was not on her wheel, just behind her. She didn't answer me... after a few minutes I realized why. She had earbuds in. I saw the little white I Pod wire sticking out of a pocket. Now I decided to play with her a little... bad. This road is flat, but has some slight rollers that require nothing more than shifting down one gear and spinning. Every time she got to one of these (there are 3-4) she stood and pushed a big gear and was rocking back and forth the way I might do on a very hard climb. Because of this, I ended up on her wheel every time there was even the slightest rise in the road. So, at one point she looks back and gives me the nastiest look I've seen in awhile, after she realized I was behind her still. Yeah, she was messing with this old lady! I knew I would be turning off on a cut through street, so I could stop and take my stuff off, so I think I was behind her for like 5 miles.
When I stopped, my average was pretty high for me, for the beginning of a ride. So, while it helped the speed, I was really annoyed. She could not hear a thing.
