Tesla's strategy is to push hotels and other facilities to start collecting charging fees from patrons thus allowing them to afford multiple chargers. These gen3 chargers with wifi connectivity will allow Tesla to collect the fees on behalf of the hotels and other purveyors while managing sharing power when it's in short supply.It probably, likely, should be an option sometime in the future, soon, eventually.
Tesla released the Gen3 with that function not implemented yet and has no schedule of when they will have it available.
