I'm all for the rollback. This whole thing is unecessary government intrustion, regulation, and bloat. Electric cars are coming, even if there is no CAFE. It only makes sense. Let the market drive it and it will wind up in the same place, withouth the government bureaucracy that costs us all money. Of course, CAFE made the left feel good and feel like they were fighting climate change, so I guess all that money got at least that.
