I drive in the same city as you. I drive Uber with model 3 STD range RWD. I drive about 300 miles in a day everyday in the snow storm. Rolling resistance in unplowed show and 10 deg f. I lost 38% range max on the worst day of driving. I take a photo of the trip every day for tax purposes, so I have proof of Kwh/mile for every day i drive. Average 226 in summer/fall. Worst day in storm i was at 370. That's 265 miles per charge vs 165 miles per charge. 38% reduction. Realize I am driving 12-13 hrs almost non stop. Starting at 100% fully warmed cabin from my garage. I'm not letting the car get cold, then starting it multiple times, which makes a difference. (Not disagreeing with anything you said in the video. Just another real case results in the same city. If I'm correct that you're in GR area.) This weekend it was just cold and mostly dry roads and I was at 284/mile, 211 range. 20% loss.
That sounds similar to what I remember my model 3 was. I did have snow tires on the 3 which loses a little energy too. One yr I tracked my Model X energy use by season and summer was around 350wh/mi or so, and winter averaged 500wh/mi. The X and Rivian def use a lot more energy than 3/Y
Under similar conditions, my 2016 Nissan Leaf will easily get double your efficiency. And here in Kentucky, we have hills to go up and down, not flat like in Michigan. That is pretty bad for efficiency. Moral of the story, keep that battery topped up as much as possible!
Driving in the mountains during freezing winter on my ID.4 drops range from 3.2 mi/kWh to ~1.6 mi/kWh. When this happens, my range anxiety kicks in because that requires more than 80% of charge to reach the next charging station on that route and 0-100% on my 2022 ID.4 in the 5F winter takes 2h+ even if it's fully heated.
