I'm guessing OP is a bad driver who is possibly intentionally blocking the left lane. Here's my case:
1. OP is going 57km/h in the fast/passing lane (way too slow for a freeway).
2. A grey car passes in the far right lane at a much faster speed.
3. OP quickly accelerates from 57km/hour to 90+km/h when grey car passes.
4. At start of video you see a bit of a white car trying to pass OP to the right, who can't due to being blocked.
5. Including Jeep idiot guy that's at least 3 cars OP is blocking by going super slow in the left lane. With the traffic, likely way more than 3.
6. Using the GPS coordinates, he's on Highway 9 in New Jersey where the speed limit is 50mph/80kph and OP is going 57km/h in the fast lane (23km/h or 15mph under the speed limit)
Obviously Jeep guy shouldn't of hopped out, but a middle finger out the window might have very well been warranted towards OP here.
