I recall reading that the Enertia display can show present current or power flow.
* On a fairly flat surface, what is the average current or power at maximum speed (65 mph)?
* What's the maximum current or power that you see, accelerating from say 30-60 mph? This might take a couple of tries to see the maximum, depending on how quickly the display refreshes.
Please do be mindful of your surroundings while glancing at the display.
