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.
A driver should get roughly the same MPG regardless of stop and go driving or highway. I get 1 MPG better in gridlocked Portland traffic than steady 70 MPH. This is partially due to the horribly short 6th gear, but this applies to automatic transmission cars as well. The average driver and conditions will hit the EPA ratings, while a conservative driver can easily exceed them. The worst tank the Camry ever had was 24.5 MPG, which was probably someone else driving.

The CAFE targets I'm seeing from the WIKI says passenger cars today should be getting an average of 45 MPG, light trucks 37, and heavy trucks 25. Don't know where you are finding the 23 MPG figure. The 2025 combined car/truck average is mandated at 54.5 MPG. My comments on bonehead regulators is based on these unobtainable figures. The gen IV Prius doesn't even meet this, let alone getting the average of all cars and trucks to meet this in 7 years.
