They were pretty crazy when I was over there in 07... though I mostly drove at night... I will say though... they moved out of the fast lane... they NEVER sat in it... as normally there was a car doing at least 110 flying by you every 2 mins...
though they never drove with their headlights on at night... just parking lights... crazy shit... you'd be driving along and boom someone would flash you in your rear view... scares the shit out of you when you don't even see headlights then BOOM they're on your tail!
