As an American, I can say that our ethic of freedom is the cause of our outgoing nature. Usually, we're friendly, funny, unreserved, and unintentionally rude (mostly). We also like convenience, a lot. That's why we carry so much with us. As for the distance thing, well, the US is big. Really big. It's why we love our cars. I apologize for the rude ones. Their parents didn't bring them up right. The rest of us are fun and want others to laugh and play too.
