Safety First

Orange traffic cones. They have many uses. I can see why they would be useful, say, if a lane is being closed or, say, you're trying to warn somebody that the bridge is out. But why do they put them in front of a broken guard rail? You know, that spot where someone crashed into the guard rail, so until they can fix it, they put those plastic cones there. I mean, really, what's the point in that? If your careening down the highway out of control do you think, "Oh, I can't crash there; there's no guard rail to stop me"?

And while we're on the subject, why do people use their turn signals when they're coming down an entrance ramp onto a highway? I mean, what choices do they have?
