Did Obama announce the end of used cars?

In his speech about the GM bankruptcy yesterday, President Barack Obama (from the New York Times) said:

And that’s why I’m calling on Congress to pass fleet modernization legislation that can provide a credit to consumers who turn in old cars and purchase cleaner, more fuel-efficient cars. (emphasis added)

Turn in old cars. It’s long been a talking point of liberals and environmentalists that cars older than a given age should be removed from the highways. The usual mantra goes “The government should buy all cars older than X and pay the owner $750. Then the owner could go out and buy a newer, cleaner, more efficient car.” The advocates for this position either fail or refuse to understand that the owners will not be able to find a car to buy with their $750. Basic economics.

Jay Leno might reconsider his support of the Obamanation if this comes to pass.
