I can't imagine what these people are doing to their cars that they're only getting 35 mpg. I average 43 in a 2002 Prius, which was EPA rated for 45/52, lower than the 2004's 51/60. So it is lower than the EPA ratings, but not nearly as bad as described in the article. And I usually go 75 mph on the freeway; the mileage goes way up if traffic forces me slower. I easily get 60 mpg if I'm going 35 mph in heavy traffic.
