Coolest site ever: Wrecked Exotics: cars you can never afford....trashed.

From this article at Reason.com:

"Economists like to play the role of academic bad boys, making proposals that spark controversy. If you want to minimize traffic accidents, a story goes, you shouldn’t look to the latest in bumper and airbag technology. By reducing the cost of accidents, these only encourage reckless driving. Instead, install a knife pointing outwards from the center of every steering wheel. Before long, traffic cops would have to start enforcing the minimum speed requirement."

My brother came up with very similar theory. I think it is gold. Ford Excursions shouldn't even have seatbelts.
