Let's be fair, now. Drivers like the ones you described are so oblivious to their surroundings that they'd do this to another car if they could. In fact, I've seen it.

I think we suffer from excessive entitlement syndrome here in the USA, an attitude that says, "It's my right drive how I want to, as long as it's legal. I don't care about the impact on other drivers, bikers, the environment, or anything else."
