It seems more like convenience to me as long as you can charge overnight and have a high enough range per charge. There could be households with complex lifestyles that share one car though.
I would still worry about this indicator for capacity though, if 100% of people were heavily overlapping on 8 hour of charging at night that seems like hours of the same draw as 15% of people who all fast charge at the same time for some reason. Whole neighborhoods might be 100% electric within a couple years of no longer selling new ICE vehicles.
