I remember looking out my window in Oslo and seeing four or five Teslas parked in a line fairly regularly. Felt like I saw a roughly even split of electric: ICE cars, but the countryside was lagging a bit.

Maybe socioeconomic factors are to blame, like having higher income means you can spend more on your car, and thus go with a Tesla. I didn't experience any range anxiety at all, there was a charger every 20 km or so, seemingly, and I traveled around the bottom half of the country.

Not sure how things are in the more remote parts, like Tromso.
