Ok, just did a run between Skokie and Pontiac IL today, 219 miles round trip. As an aside up front, if passing Pontiac IL, stop to Charge. There is a special non affiliated 4 station DC charging stop. The place "Wallys" is road trip stop heaven including a beef jerky counter, 12 slurpee flavors, and dozens of soda tap options. Retail, etc... insane. This is a vision of the future for evs.
The highway around the city bypass is 60 mph, and the route down progressively moves to 70 mph for reference. Head winds on the way down. Tail winds back. 80-84 F ambient.
3.9 miles per kWh down (108 miles) and an amazing 5.1 back (111 miles).
Here is a graph of the battery temps for the 4 hours. The DC charge added about 12F to the battery. Due to tail wind and low consumption, temp actually reduced a tiny bit on way home (maybe 1-2 degrees).

I feel like the rims help, especially when above 70mph.
