Fuel efficiency: Prius SOV vs. SUV HOV

Briefly noted: The Skeptical Optimist: The Prius gas-guzzler vs. the SUV planet-saver

It is interesting (& amusing) to examine gas consumption per passenger, but again ... data is not the plural of anecdote. The question is what is the overall auto occupancy of different vehicles. I am dubious that the SUV is in general more fuel efficient, but will be persuaded by analysis of data ... which someone should do. Lots of it is here .
