Picking up a 2016 Model-S 75 tomorrow. Used, but in great shape. Got an insane deal from a non-Tesla dealership. After extensive research (Carfax, inspection via 3rd party, etc.) decided to go for it. Now, I am in the final stages of prepping to fly down to the dealership (another state, location is 400 miles from home) and drive the car back. I just happened to find out that there is a step I was unaware of previously, in this purchase process... I have to provide documentation to Tesla Customer Support services for NA so they can "process" the transfer of the vehicle (the original owner has already factory reset the car; this is for the back-end stuff in Tesla's systems). Won't have the said documentation until I sign the final paperwork tomorrow at the dealership. This means until the transfer is done, I will NOT see the car in (my) My Tesla account online. Which also means I will not be able to use the app on my phone or anything else related to my new car that requires the user/driver to be logged-in/authenticated via their My Tesla account. So my question for all you current owners, or those who have experienced the above-mentioned first-hand, is: what should I steel myself for, that I will not be able to do while the My Tesla transfer process is occurring (will take 5-7 days)? For example, will I have issues using Superchargers? Are there any specific features on the car I will not be able to use? Heck, is it even safe for me to be driving around in it, given the circumstances?
