In my humble opinion a Prius is a toy and an expensive dead end. Its a car for Ed Begleys of the world. A rich man's "prove a point" car. I think that some are getting 40-50 mpg. I think many are not. You would have to be an odd driver indeed to maximize the mileage of a Prius. On the other hand if the majority of the commuters in the cities in which I do business, Charlotte, Atlanta, Raliegh, etc were using plug in hybrids or electric cars with a range as modest as 60 miles, a lot of gas and money could be saved.

I have two 2000 Saturn SL1 sedans. I drive a lot. When I fill up I divide the number of miles by the number of gallons, I often exceed 33, sometimes, depending on how much highway and whether I drove closer to 60 or 70 MPH I approach 35.5 mpg.
