Hi Archie,
So you question, "Is 27 mpg poor for a Prius that went 75 miles driven at an average of 12 mph?"
Lemme see... It looks like that 75 mile trip took over six hours. (75 miles/12 mph = 6.25 hrs) - That means the Prius did little more than idle its motor for 75 miles and it still got 27 mpg (Calculated by the 'puter, I presume.)
Before I give your answer, I'd like to suggest you take your fool head out of your rectum. - The world might look and smell somewhat different.
