To reach my house I travel a 2 lane road with about 10" of shoulder. The speed limit is 45 MPH. It is fairly common to see bicyclists on this road. They annoy the crap out of me. Today I was stuck behind one going about 15 MPH. Due to oncoming traffic it was about a mile before I had a chance to go around. When traffic cleared I pulled around to pass and sped up. After I was in the passing lane, but not quite even with him, he put his left arm up to signal a left turn and then almost immediately turned in front of me. He signaled about 20-30 feet before his turn. I was able to slow enough to not hit him. He had no idea I was there until he was in his turn. Of course he shook his fist at me and shouted something I couldn't hear with my window rolled up. Probably bragging about how good his spandex bike uniform looked.....75 lbs ago.
