I've also often be irritated by the slow and sometimes absurd processes of French administration, and I am pretty sure the whole thing is far from running as efficiently as it could.
That said, I gave way too much credence to Musk and his clique, turned out the efficiency theatre was nothing more than a smoke screen to cover a different style of operation.
I am not sure they even tried to cut waste in a meaningful way, or if they had the competence to do so.
