Check my fuel economy chart again.
The last run was 295 eMPG. What a drop!
I was wondering if maybe my brake pedal was sticking!
After thinking about it, that ride was all north of my house, where the speed limits are 45 and 55 MPH.
The air pushes back a LOT harder at 45 than 25 mph!!! Enough that on my electric vehicle, it reduces my "economy" by 25%.
(That's not quite the full story,
Peukert's law also is in play here.)
