Congress passed the bill back in the 70s. They’d have to pass another bill to undo it. With corporate lobbying from the auto manufacturers it’s very unlikely. They make bank on SUVs and trucks. Hell, the only model Ford sells that isn’t a truck or SUV is the Mustang.
I get lots of “Hey! We talked last week about your house! Still interested in selling? What’s your cash price?” My reply is an upscaled goatse.
