Cash for Clunkers so Successful, it's Been Suspended

The Washington Post is reporting that the Cash for Clunkers government program to turn in gas guzzling autos for more fuel efficient ones has been so successful that it ran out of money in just one week. The program has been suspended.
Turning in a car for a more fuel efficient choice is good (sans the option for us Americans to ditch cars altogether for smarter rail systems), but what happens to the old cars once they are turned in? This creates another environmental problem.
Here's a look via slide show of the trash that's created when cars are "trashed."
