LOL...I was doing the same thing yesterday at a stop sign. A guy coming towards me had his left turn signal on. So I slowed down to let him get there first, stop and make his turn. But the more that I slowed, the more that he slowed. I started twitching the front wheel a bit to hold my line and balance, making eye contact with him and even nodding my head to the right to tell him that he should go. He just sat there looking at me. After a couple more seconds it finally dawned on me that he was just going to sit there watching me track stand. So I grinned and nodded forward like I was going to move out. As soon as I did, he made his turn. I guess he was mesmerized.
