Most Californians don't know how to drive...
On the 405, 5, 10, 110, 710, 605...just to name a few...people never move outta the way if you are traveling faster than them in the fast lane. You go out towards Barstow or any other highway leaving California, and people move for out of the way for you.
And you're right...the absolute worst thing is when there is an old couple cruising 55-65 mph in the car pool lane. That lane and the farthest left lane should be 80 mph if traffic isn't bad.
oh and moron Californians don't know how to merge lanes when getting on the freeway either. they cause ridiculous amounts of traffic just because they either don't use their blinker or because they want that extra car length soooo damn bad.
