Sorry, last post was posted before I completed it!
Ok, there is always the guy whose car does better at 100 than it does at 50, but I will bet you that a Prius doesn't! Besides you are aurguing with the wrong man, I hate greenies with a passion, but I hate hypocrisy even more, and the Gores are the epitomy of hypocrisy. Not to mention two faced lying a**sed weasels.
Personally I had a Z28(1984)that did 22 miles to the gallon regularly at about 70 MPH in the Overdrive gear. Over that speed it started to suck it up pretty fast.
That's ok, I didn't mean to sound harsh or anything like that. I have a friend who has a Volvo that gets 26 mpg averaging 110, and that was crossing over the continental divide. I was talking about automobiles, isn't the Prius a doorstop, or something like that? ; )
