Well, here you go.  The perfect example of a 'holy shit', 'butt pucker' moment.  You're sitting in traffic and all of the sudden, right next to you, the ground gives way and there is not a thing you can do about it except hope that the person sitting in traffic next to you moves over just enough so you're not dangling on the edge of a hole that wants to swallow you alive. Check out the link under the picture. See how fast it happens?
