I drive my FFE a 50mile round trip (25 miles each way) mostly on freeway at 65mph+ using cruise control starting with a 100% fully charged battery.
I get home in moderate weather temps with about 20miles left on the GOM and ~33% battery charge left.
Heater not used, sometimes A/C used but not too much, mostly just fan only on at low speed (LO with A/C off).
Leaving my home for the 25mile trip is mostly downhill, so I can go faster on the freeway when I see the energy draw (wH/m) is lower on the real-time energy meter.
Coming back home though its more uphill, so I tend to keep the freeway speed down to 65mph or a little less.
On that trip, I average 250-280 Wh/mile.
On a commute if you encounter slowing during rush-hours a lot on the freeway, that will extend your range greatly.
