This honestly sounds like a failure from Tesla just making stuff work in non-standard ways.
Where I am in Europe there are a few car sharing apps that have electric cars, and all that I've rented (VW, Peugeot, Nissan, Hyundai) just work the same as ICE cars. You press the button on the key fob and it unlocks, you press Start and the car starts.
Charging was not terribly complicated either. Scan the RFID tag on the keys against the charger, plug in the cable and wait for it to show it's charging.
