How could they decentralize? There's only so much demand and available training, tho.
And yes, they have to give you the parts back if you request, at least in California.

We know that Zero is trying to do this with a European service and parts center.
But really the general recipe is that you make a process for building out expertise in the organization rather than just the people. You make sure that every incident folds feedback and improvements into documentation, training, and communication.
And you make sure that service technicians and employees don’t need to remember a lot of ad hoc shorthand to troubleshoot; instead the documents are elaborate yet clear enough that any 18 year old paying a decent amount of attention and acting and speaking honestly can do the job.
I believe this can be done because I went through naval nuclear power training as a college dropout. That’s an expensive program but the principles can be implemented given attention to detail in developing and refining written material based on technician observations and practices, including mistakes.
