Yes, the good ole "Right of Passage". Welcome to the commuter world. Now that the initiation is over, think of about what could have happen. It could have been worse at the intersection. Driver who are willing to rolled down their passenger side window are out for more than just talks after some simple word exchange. They know they have the advantage being behind a wheel. Play it on the safe side. I tried not to be side by side with those driver since they can right hook me when the light changed. I tend to stay back and not directly behind them. However there were time where my blood was boiling and I did do some bad things back to them which surprise the heck out of them
