Got a cite for that? Not disputing you, just intrigued (and too lazy to

Just a bunch of blogs. Actual Prius and Civic Hybrid mileage is more in
the low 30's for city, and high 30's or low 40's for highway. You can
get higher, if you drive slower on the highway, i.e. 55 mph, versus 65
mph. It shouldn't be surprising, as on the highway you have the extra
inefficiency of the extra conversion, mechanical to electrical back to
mechanical, without any benefit from running on batteries.

Actually in 2008, we'll see the new EPA standards for mpg, and hybrids
will take the biggest hit, about 30%. The non-hybrid mpg ratings are
going to be hit as well, but only by 5-10%.
