Action starts after 1:15. I left the beginning to show nothing happened prior to this guy freaking out. After merging onto 85 south with morning traffic I looked into my rear view mirror and saw this dude right on my ass. He proceeded to come around front of me and slam on his brakes on the interstate, causing traffic behind me to bail onto the median, then tried to run me off the road. I'm not really sure what set him off because I didn't see him until he was on my ass. My guess is that he was going really really fast, so between the time I checked the lane and actually merged (just a second or 2) he had come up on us and thought I cut him off. As you can see there was plenty of room all around and we were all merging at speed with traffic. Sorry about the music, I was watching FX's Atlanta last night so I was jamming on some Childish Gambino :)
