Discription of Events: passed me on the right shoulder going about 80 (speed limit 65), immediately crossed over all 3 lanes of traffic into left lane with no turn signals and cutting off people in those lanes. Continued swerving around lanes speeding, not using turn signals ever. Back right tail light was broken. When he saw I was looking at his license plate he waved his arm out of the window and flipped me off and zoomed away.
