You can purchase a three-phase 230V / 80A wall charging station from Tesla.
If you are running a fleet and need a lot of capacity, then you can throw money at Tesla and get a private supercharging deployment (they've done it before).
But if car is resource not to be wasted it would be driving Uber pax 24/7 minus charging and maintenance. Maybe 3 drivers per car. Sure, fewer pax at 5am but probably dependent on what city/market.
This is a business decision of the actual car owner.
