Hmmm, I saw this & immediately went & checked the lists of cars in the "garage"; 28 gasoline and 16 diesel cars (not hybrids) all doing better than 50 mpg.
Furthermore, there are 110 gas, 13 diesel, and 4 hybrid cars more than 30% over EPA, as well as 13 gas and 6 diesel trucks more than 30% over EPA
If that's a "joke", I want in on it!!!
