I recently took a road trip from CA to NY and back. As soon as I got out of CA, people were obeying the "left lane is for passing" idea -- except Vegas. I spent weeks in highway driving bliss with pretty much everyone obeying this rule. Then when I came back, and hit CA, I was immediately pissed off at traffic -- nobody was following this rule. But at the same time, the traffic is usually so bad it makes this rule meaningless, so I think we just forget about it after a while.
