Other than the small range decrease because of the cold weather, how does that differ from an ICE car? His comment was about swapping cars at the charger with cars buried in snow, which isn't an issue when you no longer need to swap cars because they are charging at their own spot (per my comment about adding L1 charging to a large portion of the spots).
I guess if you're for some reason running your cabin heating the whole time then I suppose you're reducing your range, but that's solved by not doing that perhaps.
