According to Viking, a road assistance company in Norway (think AAA or Statefarm roadside assistance), EVs are a smaller share of their overall assistance calls when compared to the gasser-counterparts in relation to Norways overall percentage of EV vs non-EV vehicles, as reported on Electrek.co.
Approximately 23% of the cars Norway are electric while only 13% of the road-side assistance cases were EVs in the first 9 days of the year.
Now there could be many reasons and explanations for this, but it is solid anecdotal evidence that EVs are great vehicles even in the deep cold regions.
