Car standards started in 1978
The goal was to double the 1974 passenger car fuel economy average by 1985 to 27.5 mpg in small increments.
1978 18 mpg
1979 19 mpg
1980 20 mpg
1981-84 22, 24, 26, and 27mpg
1985 27.5 mpg
1986-1989, passenger car standards were lowered.
1990 27.5 mpg, where it has remained
Looks like I'm average for US fuel mileage standards. The gas guzzling tow vehicle and my racing consumed 94.71 gallons last year (tax write off, so I have all my receipts). I bet I use less gas than 80% of Americans (last years total mileage for my 1995 was 4207 miles), I don't drive much (very short commute), only skiing burns a lot. If Subaru was forced into better fuel mileage standards then my Subaru would get better mileage, not gonna risk my life in the mountains for 10-20% better mileage.
So; what's your point? You trying to throw something that's not going to stick
