You seem to be ignoring the fact that the battery pack status after a crash is essentially unknown. It should go through a thorough and competently conducted safety inspection or it may kill someone in the future. Of course, this doesn't excuse extra red tape tacked into the procedure, but the core idea of an inspection is just unavoidable.

That's exactly it. I understand the importance of safety but reading the list of complaints I just cannot believe that safety is the key driver for the design decisions.

Everything about this screams greed driven over-engineering. Since when are error prone processes and lack of access to information better for safety?
We live in a world where everyone justifies taking user hostile actions with some variation of "safety". Software and hardware are locked down, backdoored, need manufacturer approval to operate even when original parts are used, etc.
I won't go into details about 'training access for ISTA usage' - cause I don't know what exactly Vanja means by this - but generally speaking in EU BMW provides the easiest access from all OEMs for aftermarket repair. Everyone has to provide it by law, but BMW has the most straightforward way of registering/paying/using it. For sure not ideal, but far from really being problematic IMHO.
But other than that I mostly agree, I don't think that the over-engineering is greed driven - but the EU Manufacturers (but honestly, even other ones) have a really hard time with anything software based. Be it in car or outside of it. But BMW is far from the worst on that front.
P.S: VW ODIS original diagnostic is based on Eclipse :D
My experience with many German mechanical and electrical engineers is that they have a tendency to think of software like a magical cheap and malleable part on a BOM that can make their arbitrary design work. Especially the mechanical engineers like a nice little black box that they screw on and wire into their machine to make it go brrr once they turn it on.
That kind of thinking along with some calcification of organizational structures in/around R&D teams seems to be the cause for the rather dysfunctional software development at the German car companies. Software dev doesn't thrive in this environment.
Volkswagen probably had the right idea on paper when they created Cariad as a subsidiary software development company to isolate the devs, but then they ruined it by importing their own culture into it again.
