To me, this sounds like a good old Conway's law. The EV fundamentally changes the architecture of the car: what it's made of, what's the role of each component is and how these are interlinked. In particular, there's a shift from mechanical coponents to software components. This would imply, that the structure of the organization designing the car should also change in fundamental ways. But in absence of an enterprise architect (as in "a person responsible for the architecture of the entire enterprise"), it can be tricky to synchronize organizational change with engineering change due to separation of responsibilities. Also, interaction of physical components is rather straightforward to determine (separate teams for the battery and motors is obvious) whereas software components are intangible.
