Tesla? Really? Have you actually worked on one and tried to get parts and tools from Tesla? There is a reason why tools like LOKI exist and it's not because Tesla is as forthcoming as you describe it. Tesla is actually way more restrictive on things like parts than Volkswagen, they will not sell you any parts even if you are an independent shop unless they deem you worthy.
That is not actually correct. I've bought a lot of parts from them. They even offer their parts catalog for free and in many countries you can even order directly from the catalog. In Finland you need to order them via service centers.
Also I don't understand for what you would need LOKI for? Maybe really old Tesla vehicles?
Now it's enough that you have ethernet cable and laptop with web browser. You then buy diagnostic software access for 75$ a day and you get access to complete vehicle. Only thing you cannot do unless you're an authorized repair shop, is replacing parts that are involved in vehicle or backend security.
But you can run diagnostic routines, output tests, replacement procedures, configuration changes etc etc. Also there's a really good guided function to check if there's a real problem flagged by vehicle alerts.
How you do it with VW. You first apply for permission to access the diagnostic network. That will cost you 2000€ here, just to apply. Then you apply for brand (if you get past the first phase), which each brand costing around 1000€ per year. And to get to this point, you also need to pass security audit. If you pass all of them and pay up, then you can start using and factory connection. Of course you then also need to pay for a diagnostic session which is roughly 25€ per day.
Of course they will grant you access to IMMO and other security functions as well. But to me this sounds like that it is not really supporting the "right to repair" act very well.

On the other hand there is FCA where you got no information or paper of regulation to use different wheel or something similar.
Or "old" Opel (GM based cars), where a lot of things aren't available anymore. Things like PIN Code, or genuine parts which are important to use the car. And this happen for Insignia or Astra J, where some of them actually not reach the 10 years mark.
And this are just some easy example.... VAG is not really good in these things, but much better than most of the other brands actually....
Fair enough. I didn't know that about Opel. Interesting that they are doing what you wrote, as 10 year availability AFTER the production of the car has stopped is regulated by law.
