This car almost collided with me at the entrance to the Manhattan Bridge (Manhattan side). This apparently made the driver (and at least one passenger) very angry - so angry that the driver of the car chased me down, slowed down next to me in the left lane (mid-bridge), and threw an unknown object at the driver side of my car. My two children were in the backseat at the time, and this object could have easily injured my children, me, or caused a serious accident.
