I suspect the OP has a city commute. If that is the case then 22 mpg is about right. If that is highway mpg then something is very wrong with the car or the driver's foot.

The best way is to simply increase the federal taxes collected on every gallon of fuel, and then reduce income tax in proportion.
Increasing the gas tax would be the most direct and effective way to reduce fuel consumption. It would also be a very unpopular way to do it which is why politicians chose the much more convoluted way of doing it through CAFE.

The recent drop in fuel prices would have been a fantastic time to put a floor on fuel prices by increasing the gas tax.

Yes, everything is subject to diminishing returns but we are nowhere near that place with fuel economy. Regulators are far from boneheads. CAFE targets are set in 7 year blocks and progress is reviewed periodically. In 2016 the EPA found that automakers were ahead of schedule but left the future targets the same. By 2025 a F150 will need to get 23 mpg combined. Today trucks are getting 22 mpg so 1 mpg in 7 years doesn't seem like a very lofty goal.

The Fusion Hybrid does get good mileage and is very reasonably priced at about $25k. I've had several as rental cars and they drive well. It is a perfect example of how to easily hit future fuel economy goals using current technology. Why isn't the Hybrid the standard model instead of 2.5L 4 cylinder that only get 25 mpg?

Pretty much every automaker has a similar vehicle:

52 mpg Toyota Camry Hybrid
48 mpg Honda Accord Hybrid
46 mpg Chevy Malibu Hybrid
42 mpg Ford Fusion Hybrid
41 mpg Hyundai Sonata Hybrid

The question then is if a Honda Accord can get 48 mpg why does a Honda CR-V only manage 30mpg. The Ford Escape is only rated at 26 mpg. This is low hanging fruit. These should be in the mid 30's and they will be soon.
