I think if you're in the left lane only going 1 mph faster than the cars in the right lane, especially in traffic, something is wrong. Especially on interstates where lanes are typically wide and the road relatively straight, and in good weather & visibility, if you have any appreciable amount of traffic on the road it's much better to go 5-10 over to pass then get over to the right and go back down to the speed of the right lane than it is to be in the left lane holding up a line of traffic while you take 5 minutes to pass one semi.
