Discription of Events: The male driver was furious because I was waiting for traffic to pass. I was first in line to turn left leaving a parking lot at 40th st & bell. He went into the right turning lane next to me, flipped me off & had cut in front of me while turning left when traffic was clear. I turned into the left lane heading in the same direction keeping my distance. He started breaking suddenly so I switched lanes, then he continued swerving in & out of two lanes as I tried avoiding him & continued to press on his breaks.
