By the way, I followed your link, as 20% sounded low to me. The pie chart on the source says 23,6% of all cars in Norway is electric.
Which is more in line with what the State Road Authority said in July this year: We are approaching 24% electric car ownership.

Considering over 80% of new cars sold are electric now, my guess of 25% now is probably accurate. We will see when new numbers come out next year.
20F is -6C, which would be a mild winter day where I’m from. And honestly, even with those temperatures and snow on the roads I don’t notice that much range loss in my 2021, compared to losing almost half in my 2019 without heat pump.
Tests in Norway show a range loss of around 6% in newer Teslas during winter.
