Any studies being done looking at the Prius cab mileage, and battery life? Prius cabs in Chicago were a rarity a few years ago now they are everywhere and used by just about every cab company.
700,000 km on the battery http://priuschat.com/forums/gen-ii-prius-main-forum/79235-299-999-mile-club-21.html
And I figure the taxi wust still have been in great shape since they had a car with 700 Mm on it and they still spent the coin to put in a brand new battery! Edit... sorry, thought you were referring to the cab in Canada that has a gigameter on it after changing the battery at 700 Mm.
