My Triumph RS....actually most of my motorcycles since 1975, can get 52 mpg average ( high/low/cruising), still tops 150 MPH, and is always at least 50% of carrying capacity.........
So, you'd probably have to drive your Prius/Volt crappy hybrid about 900,000 miles to save all the gas )I have, over the years......oh, and weighing 450 lbs means it doesn't damage the road infrastructure much, either
