I don’t see any big psychological thing about it. The older I got, the more responsible I got, the less need I had to drive fast and depend on people clearing out of my way to get places at the speed I would have liked.
Responsible drivers don’t try to impose personal order and take revenge on the world by squatting in the fast lane.
It isn’t up to you to worry about why the world is driving faster than you, and need to get by you, just be responsible and try not to block traffic flow, set ego aside, and let the traffic flow at it’s own natural rate.
It is also incorrect to keep saying that lane blockers are at the maximum speed, and that they are only blocking speeders, in real life that is by no means always the case.
