This is so cool Phil!
We should post this to our website.

I'm trying to plan a trip to DuPont, and this could come in real handy.
Some rather steep climbs at freeway speeds won't be too good on my KWH
I try to use a rule of thumb to say the LEAF consumes an extra KWH of
energy for every 700 ft it climbs.
(I'm not counting the downhill recovery.)
