What happens to most of us, in most driving conditions, is that we’re losing some of the key attributes that facilitate human cooperation and, in a larger sense, society. Eye contact, for example, has been shown in any number of experiments to increase the chance of gaining cooperation — that’s why when drivers give you what was called on Seinfeld the “stare-ahead,” your chances that they’ll let you merge in ahead of them are greatly reduced. Then there’s the anonymity in traffic — there’s no one to spread rumors or gossip about you about how bad your behavior was — not to mention the lack of consequences for acting like an idiot. It’s all strikingly similar to the way we act on the internet, in what’s called the “online disinhibition effect.”
