The companies are young still and have grown quickly. I think we are coming up against the organizational maturity/size limits of what much methods can do. Running a few dozen or a few hundred people is a different thing entirely from running something so large.
The biggest impediment to this level of growth is propagating the mindset of Elon to his subordinates. Generally, people make decisions that weigh to some degree upon emotion, rather than strategy. Much like investing is undermined by emotion interfering with strategy, it is challenging to encourage people who are not "on the spectrum" to isolate their emotions from the process.
This is likely what causes issues like we saw with the Supercharger Expansion Team.
Elon is dependent upon others, simply because you can only spread yourself so thin. Though Tesla's use of an AI app for employees that helps coordinate all aspects of operations, communications, and planning between groups and individuals very likely helps immensely.
I expect that as more AI and robotics are deployed there can be improvement at an exponential pace. This contributes significantly to aspects of the pivot towards a greater focus on AI and robotics being so very, very important to Tesla's continued growth and success.
This is something those who only see FSD improvements as the goal might be missing when they voice concerns over what seems to them a pivot that abandons the existing operations. This pivot will offer boons to every corner of Tesla.
And corporate culture is something to design and tend carefully, not ignore.
But yes, you have valid points. It will take a few more years for the dust to clear on this.
What if people holding a mindset as you demonstrate are unable to weigh such views against the long-term success of this corporate culture and the results that it has netted for Tesla, both up to now, and into the future?
Being able to envision doing things differently is a bonus for Tesla because it brings positive results faster than the methods being touted as if they offer some advantage.
This elusive advantage you allude to for some ideal corporate culture is one that does not reveal itself as being as successful over time when compared to the progress Tesla has achieved with their style of management, now being expanded upon with AI and robotics.
Welcome our AI overlords, as this corporate culture will inspire productive employees to meaningful greatness while simultaneously and quickly migrating non-productive employees to find work somewhere else, perhaps in a corporate culture more akin to the one you describe.
