I encounter the same problem....I get
super mad road rage!!!
I even do stupid stuff like tailgate the slow pokes and rev my engine till they move...I gotta quit doing that.
I've noticed other states are different. When I've driven through Oregon everyone is soooo nice! They get out of my way and even wave me by sometimes! But the second you cross back into California, ppl turn STUPID!!!!! There's a whole row of cars in the fast lane and NO BODY in the slow lane. I usually cruise at an acceptable freeway speed in the slow lane and curse all the fools to my left as they eat my dust.
