Hussein would have everyone driving a Prius or 2 seater soup cans powered by a lawn mower engine with the 54.5mpg requirement and they would be more expensive than the real cars of today. How many cars achieve 54.5mpg today? Maybe a Prius, or a Leaf (discontinued) or Tesla before it catches fire. Inevitably this was another decree with the purpose of transforming America into a 3rd world country. Used cars (with size and power) would be more desirable than the new car lineup, older cars in good shape would be in great demand.
