I dunno if it's called a "Fast Lane" or a "Passing Lane" but I've driven in states that if you don't treat it as a fast lane, you'll get your ass run off the road. Once you get in the fast lane, you stay there and you best keep up! Try playing that "Passing Lane" crap on a busy eight lane freeway, you'll be lucky if someone doesn't drop a Mario Kart banana peel on ya.
