So? The majority of Teslas aren't sold in SF. Having access to instant-on heat, rather than having to wait several minutes for the engine to warm up, is absolutely a benefit in places with cold winters.
I'm trying to redirect the conversation back to things that matter. The weather in SF last night doesn't matter, not really; it's just some ephemeral fact, and not even worth arguing about whether someone "needed" instant-on heat for it or not. What matters is electric vehicle models and sales worldwide, which is what the top-level article is about. Tesla is the most popular car manufacturer in Norway. You better believe that they appreciate instant-on heat there (as well as remote start), and that Teslas having these features gives them a competitive advantage.
