 We know nothing about that part. Then what do we do? Subtly, we're annoyed that we get up right on their rear end and they move over. Finally, get up! But it's our fault, too, for sticking around, because we should just gun it and get the heck out of there. We always slow down and turn to see. I never do that. Because they look as stupid as they're driving. Isn't it amazing? The weirder they look, the more it made sense when they were driving.
