Right now there is not any Tesla service centers anywhere near where I live. That might change when Model 3 deliveries start, but here is what I hope the future Tesla service experience is like. I set up a service time. Tesla sends an autonomously driven loner vehicle to my house. Loaner arrives and my car drives itself to the service center. Process is reversed when service is complete. Tesla gets high marks for the service experience now - imagine what it would be like with that kind of service experience. The only time I would have to actually visit the service center is if the advanced autopilot is the system that needs service.
