>​Just because you think your are justified in your speed in the left lane because you’re inching past the middle lane doesn’t mean it’s lawful.

Seems like a contradiction, if they are still passing traffic on the right then they are being lawful. That's what I see 99% of the time during my daily 1 hour commute, cars in the left lane slowly passing cars in the middle lane. Except the cars passing on the left aren't passing fast enough for some, even though the regular flow of speed in the left lane is 10-15 mph over the limit. At that point I won't harp on who is breaking the law going over the speed limit as I regularly follow the flow of traffic just like most do.

I just wish that drivers would understand basic physics and realize that cutting off someone leaving a 2 car distance in front of them means they are still stuck in that same traffic lane at the same speed, maybe they will get to their destination 0.0000827 seconds faster. It's really rare I see someone get ahead a few cars, and then magically the highway opens up into total open road.
