While in no way minimizing the terror that must have been extreme among the drivers and passengers of these 200 vehicles as they slowed, slid, and slammed into one another on I-94 (near Battle Creek, Michigan), one can't help but analogize to the two most crowded trades in the world right now and what happens when the traders' "liquidity" is the same as the drivers' "visibility."

If you've ever read one of those "ten million car pileup on [insert Midwestern highway here]" stories and wondered how it happened, this video of I-94 near Battle Creek, Michigan from yesterday should help explain it. Visibility is so low that once a couple of vehicles wreck, the ones coming behind can't see them until it's too late, and they helplessly slide into each other and become one giant katamari.

As the second half of the video demonstrates, these wrecks are goddamn scary and dangerous. In this particular one, the Detroit Free Press reports that one person was killed and two dozen taken to the hospital.
