I am a legal resident in, and citizen of, two countries the US and Brazil. When Tesla opened up Model 3 reservations to include Brazil I immediately placed a reservation there using all my Brazilian data, including all the identifiers and contact information there as well as payment from there. Two days after MyTesla showed my current S, my US 3 reservation and my Brazil reservation. What is more MyTesla now shows all my US contact information as "primary" and all my Brazil information as "Alternate" I have dealings with five international airlines, four hotel chains, Apple, Amazon an others in both countries. None, repeat, none of them manage to automatically distinguish between international addresses, nor even link them at all! Even ones I use in both countries must be manually changed between two independent accounts in order to handle the most mundane issues. Most of the airlines and hotels cannot accommodate different address systems, telephone protocols or naming conventions within the same customer record. Here is Tesla, a company logically linked to a single country for a single relationship that automatically makes the link and does so without even a request to do so. What's more it is correct the first time despite a slight difference in the way my name is presented, different address structure, accent marks etc. I was already very impressed with how Tesla handled my customer issues. Now I am blown away. Today came a final fillip: My US S is needing an annual service (prepaid) when I will be in Canada. Figuring I would need to return to the US for that service I called tesla anyway. No problem, they say, just book with the Service Center you choose. It's all linked. Wow!
