And based upon your video, due the difference in your speed and the white truck you passed, it is highly probable you had plenty of clear space to move to the adjacent lane. I suspect if you had turned on your turn signal he would have yielded to you and allowed you to pull over. If there wasn’t, you have brakes on your car? You could have slowed so as to be able to pull in behind the white truck
Unless everybody else was driving way below the speed limit, you were actually speeding. There was only one vehicle in your entire video going faster than you and that was only until he got caught up in slower traffic, which was presumably moving at least the speed limit. It appears you did slow down, a little bit but less than any of the other traffic,which were in the lanes that allowed them to drive the speed limit.
btw: most, if not all other states have similar laws requiring you to move over or slow down when there is a cop alongside the road.
