Re: 42 mph Threshold & Block Heaters
Good point Bob - the built-in cruise control on the Prius is certainly guilty of exceeding 2500rpm on hills on the highway - man that's messy.
I simply don't use Cruise Control because I'm always driving rolling hills, and instead try to maintain my foot position on the Accellerator, causing me to decelerate going uphill and accellerate downhill. At low points in the drive I might be doing 75mph, and at the crests of hills I might be doing 60mph, but I can hear the gas engine rev at a relatively constant, reasonable rate the entire time - certainly below 3500rpm, and I would guess around 2000-2500rpm.

Re: 42 mph Threshold & Block Heaters
Sort of - I think you just have the arrow colors confused but get it just fine. If you accellerate gently a red arrow comes from the engine to the wheels, and a green arrow comes from the EM to the battery. If you see a yellow arrow between the EM and the battery, it's going to be pointing the other way - at the EM - and that means you're harming your efficiency.
