I'm oversimplifying here, but carmakers do need EV divisions to bridge the gap. They need to be independent but be supported by the top of the organization. There's way too many stakeholders involved in the ICE orgs that could hamper progress here.

Another thing - these companies need to commit to building actual EV-first platforms instead of doing the weird platforms that supports both ICE and BEV which come with tradeoffs in packaging and driving dynamics.
