Unless they try to outlaw gasoline and or ethanol fuels we don't HAVE to do anything. I always kinda scratch my head when people say "we don't have a choice".
What if Dodge, GM, and Ford all told the gubment "hey we can't meet those cafe reqs, wanna rethink that before we shut down production and close our plants costing tens of thousands of people their jobs?"....what would happen then? The reason the car companies aren't doing that is because they're getting kick backs of our tax dollars to make electric cars and they want the cash grab. Tell me I'm wrong.
