Looking at that graphic, it's a not about being the fastest boy. You just have to be going the speed limit or higher.

So if I am going 62 in a 60 passing cars going 40, in seemingly almost all of the states, I absolutely don't need to slow down to 40 and get in the right lane just because some fuckstick wants to go 95. Many people act as if the left lane is a special road for fucksticks who go 95
