Price George, BC? Yeah, no.
But given how popular the Teslas are in Norway, I think there's probably hope. Even if we're just talking about the little cars at first.
Once the batteries have sufficient capacity, you can just devote some of the spare capacity to heating during a trip.
In theory you could also have a dedicated heater than ran on LNG or similar. Might be a "less bad" compromise to enable EVs in such situations until the technology evolves to go full electric.
