Do you think these results are at least relative to the advertised mileage? That would be all that would matter to me. If I bought a new car, I wouldn't compare it's EPA rating to real-world results on my old car. Instead, I'd pretty much just observe the difference in what I was paying on average for gas

Did they test other cars, like minivans? The new Odyssey suprised me recently. I could be totally wrong here, but I could swear that I read somewhere that it was possible to select to only use four of the engine's six cylinders in order to save on gas. I don't know if this is true or how it is done, but it's an interesting idea...
