They are if you take their parking space or cut them off in traffic. I brake checked one once he was inches from my ass. He chased me down the highway we finally pull over. He starts yelling in nasally Australian. Still no idea what he was saying til this day. I said shut the fuck up. Your the asshole that caused your own problem by riding my ass! Something mumbled in incoherent aussie something about fuckin yanks. He drives off.
