The driver of the vehicle pulled into the traffic, cut me off. Then he and his passenger-female- proceeded to assault me by showing the middle fingers while kept driving on front of me. At the traffic light they would roll the vehicle back and forth trying to scare me, as it was getting close to my front bumper. All this time they have their middle fingers sticking out of the windows. It all started at 1221 Brickell Avenue up to they took off on the SW 7 St by making a left turn.
