Toyota is over invested in technology which has been overtaken by newer, better variants. They bet early, didn't see the promised gains, and their leadership have reduced faith in the likelihood that battery tech will be able to turn a profit.

I suspect they will be caught with their pants down and will need to resort to using someone else's supply chain to fulfill demand in the future. This will push the cost of their own supply chain up, and they will become increasingly less competitive and lose market share because of it.
