If you were a car company why wouldn't you? The govt has proven it will step in and make taxpayers foot the bill for your bad business.
How does this put the car dealer on the hook? At the end of the day, if you file bankruptcy or default, its the lender, not the dealer, who is the loser. Unfortunately, as we've shown, the lenders will be bailed out for making bad loans. Even more unfortunate is that they probably should be bailed out because the government will sue them for discrimination should they choose to not lend to the credit unworthy.
