Some cabbies are completely clueless. I say some cuz I've encountered some courteous ones as well. I was hit by one cabbie's side view mirror once. Not enough to hurt or even leave a mark, but it made contact. So I knocked on his window and yelled to him that he hit me. He said something I couldn't hear and the passenger in back threw her hands up like she couldn't believe I was going to delay her from getting where she was going to. Of course I had to yell b/c the cabbie never rolled down his window. So I figured a visual would be more effective. I stared at his medallion number, pulled out my phone, typed it into a text message, then smiled and rode off. He probably ***** his pants when he realized he could lose his license.
