Although, if you’re in the left lane and someone manages to pass you on the right, that probably means it’s okay for you to move into the other lane...

If someone passes you on the right, they’re an asshole. If everyone passes you on the right, you’re the asshole.

On the other hand, people don’t have a right to drive ONE mph over the speed limit. Not one. The left-hand lane is not the “laws don’t apply to me” lane, and people need to remember that too. If you are a criminal reckless driver, that’s not the responsiblility or problem of the law-abiding safe drivers around you.
