On a roadway with three or more lanes going in the same direction, which lanes usually offer the smoothest flow of traffic?

Smooth driving allows you to keep more distance between yourself and other drivers. It also helps save gas. Where there are three or more lanes going in one direction, the middle lanes usually offer the smoothest flow of traffic. The left lane is for drivers who want to go faster, pass, or turn left. Slower vehicles and those turning right should use the right lane.
