Isn't that 55 MPG EPA, a CAFE (Corporate Average Fuel Economy) standard and not every manufacture's vehicle? Some if not most of those hybrids are in place just for CAFE and the manufactures will just keep making more models to keep inline with CAFE and still build those gas guzzlers to within 1 MPG CAFE to meet it. I know personally how Honda for years had over 58 models of motorcycles per year that as corporate averaging would meet emission standards by 1 gram over the total model line. One of the bikes was an almost race emission model that was even over the national limit and still able to be sold......except in California. The manufactures that want to keep selling low MPG and high emissions vehicles will figure it out and is some cases the consumer will pay the "gas guzzler tax" and drive what they want........and some will still complain Please everyone keep buying those hybrids and EV so the rest of us can still have our polluting gas guzzlers
