China (yes, that China) gave it a go and, sure enough, it increased demand.
The United States is taking a much different approach. See, we shovel money to the car companies, guaranteeing that supply won't decrease. We aren't doing a damn thing about demand because, well, who needs demand as long as the union workers can still collect a paycheck?
Those taxpayers that would have bought cars will have to pay more in taxes to cover the automaker bailout, which seems like the sort of thing that would decrease vehicle demand even further.
Call me crazy, but I still think the automaker bailout was a bad idea, and any future bailouts of automakers are bad ideas. Let them file for bankruptcy, split up the company, drop cost centers, and realign supply to meet with lowered demand. Keeping supply alive to meet some future demand is akin to flushing money down the toilet. The worst part is that we aren't even getting cars for the money we throw at the automakers. All we get are the same open palms a few months later asking for more.
