Road rage man, road rage.
I'm a fairly decent driver but I make mistakes. Only problem is, when I make a mistake, Dude affected by it thinks I'm an idiot and the worst driver in the world. Let's assume Dude is a decent driver but makes a mistake and Bro is affected by it. Bro thinks Dude is an idiot and the worst driver in the world. Then Bro makes a mistake and on and on and on. Pretty soon you got a bunch of people who think they are decent drivers surrounded by idiots.
But seriously, get Canadians off the road. I'm kidding, we all know Canadians can't afford cars. You know, because of their powder habit. And by powder, I mean snow. And by snow I mean cocaine.
