Yep, an excellent reason for government to stay out of business.
So:
The taxpayer is on the hook to bail out GM in the first place, but then they are further nicked as GM (at Obama's behest) produces a car that no one wants, and is pretty much a lemon. The taxpayer continues to subsidize this car by giving tax credits to defray the cost to the buyers of these vehicles. On top of all that, the taxpayer (through the government)actually has to buy the car in order to puff up reported sales figures. Many of these vehicles will likely be parked, rusting on some unused tract of federal land in Nebraska.
And some people wonder why we don't think much of Obama's economic acumen.
