Today driving to work I merged onto 95 south (in Bangor) behind a van. As soon as we were both in the right lane he merged into the left lane where a bunch of cars already were behind us. There were zero cars in front of us for at least a half mile. I ended up passing him on the right. Seriously tho why would he want to go straight to the left lane after merging when there were no cars in front of us???? He was still in the left lane doing about 65 every time I looked in my mirror until I was too far ahead to see him anymore
