My 35 floors building has exactly 2 chargers. Both are FIFO, max 5 hours or you start parking and both are slow af and pay for charge. Charging M3 on one of those is probably a whole day activity and would cost you probably more than if you get a diesel generator running to power charger.

So I might not know those people, but know of at least 10 teslas that aren't charging at home every day, because usually those spots are taken by polestars.
