You need to be glued to the right lane though, or be willing to speed while passing even slower traffic, or you will definitely mess up the flow.
What really messes up flow is traffic "waves"[1] and these are often caused by drivers hitting the brakes because they're following too closely or someone cuts in front of them aggressively.
