What speeds are you guys driving at to get 58 MPG on cruise control? I just drove 240 on NY interstate highway and ended with a 42MGP count. I was cruising around 80 MPH with cruise control... too fast?
For me to get 58-60 MPG would require a warmed up car plus no hills plus cruise control speed of 75-80 km/h (= 47-50 mph).

Does driving in electric really improve MPG? Sure, while you are in EV you get infinite MPG, but that energy had to come from the gas engine, only now through inefficient conversion from gas to electric to battery to electric to kinetic.
From what I have seen on my Prius, using the EV switch does not improve the MPG. I use it now only when for about 200-500 meters after leaving the parking place and same distance upon arrival.
