As a mechanic and a driver that actually likes to monitor engine gauges - I feel a little naked with so few indicators of how the engine, transmission, cooling system, etc are doing on the Prius. "Idiot lights" have their place as most drivers don't watch oil pressure or coolant temperature anyway - so lighting up when there's a problem is more useful to them. However, knowing what a normal oil pressure or coolant temperature is can allow an operator to see problems before they become serious. Seeing needles on a gauge right where they belong can be a reassuring thing. Having used a bluetooth OBDII dongle(?) and a smartphone app (Torque Pro) I know there are a bunch of sensors and values you can monitor on an ICE car - stuff i never knew was out there. I see from the Carista App, that there's "No Live Data" available on their app for the Prius. I'm guessing that means that you can't monitor that kind of data on a Prius - at least not with Carista. Have other owners found a fix for their gauge habit?
