At least up through Gen-3, all mileage readouts I know of "peg" at 99.9MPG. On the other hand, once my P.Prime arrives, I intend to run it on electric almost all the time. If they all peg at 99.9, they will effectively become meaningless (or at least the long-term, cumulative ones will). Do all of the P.Prime mileage readouts "saturate" at just under 100MPG?
