I don't really have an issue with taxi cab drivers in general, but this one seemed to be going out of his way to annoy me. I figured I was tolerant considering that I allowed him right of way when he didn't have it when he pulled out on me. That's self preservation anyway, bike vs car is a losing proposition for me. Then he kept on doing whatever he could to block & inconvenience me further and I let that go too and the last straw was the horn beep, I only looked over at him because after the first 2 stunts, I wasn't even sure or comfortable about the next move he was going to try to do ?
