Well I'm not a tree hugger but I do own a prius as my roundtrip commute to and from work is 220 miles. I set my cruise control at around 80 mph and I get about 43 mpg. This is a lot better than my Suburban which just kills me on gas.
On the other hand I know how you feel because when I'm in the HOV/carpool lane the car that is usually traveling slower than regular traffic is a Prius...and it is usually around the Berkeley CA area.
I'm gonna purchase a new SPF as soon as I figure out what color I want. I can't wait.
