Adding another datapoint:
I just received my MYLR. Currently WFH, but when we return, I expect my wife's commute to be 20km one way, so ~40-50km round trip per day. In current weather conditions in a reasonably weatherproofed (but NOT climate controlled) garage, I get 7-8km/hr, so overnight 10h charging during off-peak times is an easy 70km. More than enough for a round trip. My house is 50+ years old, so upgrading to a 200A panel will require trenching a new main line from the city ($$$), and there's no room in the panel. At least the outlet I'm using in my garage is not load shared with anything, so the car can always happily charge at 12A/120V from the NEMA 5-15 outlet.
In this case, I'm "letting it be" on 120V/12A and if it becomes a problem in the winter, I'll deal with it then. Whether that's a 240V 15/20A charger, or an entire panel upgrade - we'll see.
For reference, in the dead of winter (-20C) my garage gets to about +8-10C. The garage door is very well insulated, but there's no HVAC going into the garage, so no way to "maintain" a consistent temperature.
