Just Squeezing Through

Just as I was changing lanes to get around traffic, I saw someone approaching at a high velocity. I did the courteous thing and let him pass. After all, slower traffic should not be in the left lane and if one is passing in the left, they must accelerate to how fast cars are already doing in that lane so as not to cut off traffic.
I then witness the car performing acrobatic feats of driving all without signaling. Please folks, use your signal light and move over to the right lane for traffic that is driving faster than you, regardless of to what speed you're driving. Do not block traffic thinking you're driving the speed limit or already going faster than it. Do the courteous thing and let traffic that is faster than you get by.
It goes both ways. If you are driving faster than traffic, please change lanes to pass other cars before you start riding the tail of the car in front of you. Note how I changed lanes near the beginning of the video before I made it to the car I was passing.
There are only two modes of driving: Get out of my way mode, and get off my tail mode. Do not think you are in the right if you're driving slower and you legislate someone else's driving for them. You are not the law and your obstruction to traffic is as dangerous as multiple lane changes are in high density traffic.
