I was talking to my brother on Thanksgiving, and he mentioned a federal scheme that is (as usual) being abused--A subsidy on electric vehicles can be fairly easily used to get a free golf cart. The dealer puts bumpers and lights on it, the Feds accept that as transforming it into an "electric vehicle" and the subsidy equals or exceeds the cost of the cart. You don't have to actually use the cart for anything.
I thought Cash for Clunkers was about as stupid as they could get. Now I only wish it was.
