Aggressive driver. Put on my signal with plenty of time to enter left lane of highway. Driver sped up and was unwilling to let me in. When I finally turned in the lane, even putting my hand up in gratitude, the driver tailed me and then switched lanes and cut me off. He stopped on the left lane if the busy highway, got out of the car, and came out yelling, swearing, and saying racist remarks. Feared for my life.
