Well, frankly, Northern Maine isn't very much north and not enough inland to get the extremes?
Most of Scandinavia has been below -15F for a good part of the new year and being relatively dense (for Scandinavia) in EV coverage I'd say Norway is the best example of EV very cold weather performance.
We've had this same "debate" here as well with ice-owners lamenting the perceived loss of range and EV-owners responding "I know, don't care. Always works, always warm and always topped up".
And it would be so much better if that something was something others actually find interesting. Instead its something esoteric like energy storage solutions, or the difference between b550 and x570. I was once asked, "what's the difference between m-ATX and mini-ITX?" And I knew way to much about it to be socially healthy...
