Here in the DC area during rush hour the fastest lane on any 3 or 4 lane interstate in stop and go traffic is generally the right lane and the slowest the far left lane. This is exactly the opposite of what you would expect. You would think that the lane that has the cars merging in and out would be the slowest lane but in fact the right lane generally only slows right at the merge point. Some people will switch over to one of the left lanes there but I find that just staying in the right averages out to the fastest.
