If they had a hydrogen source for cheap, it would have been so much easier to just transform it into hydrocarbons. They're easier to store, easier to transport, and all of the existing structure is already built around it. Just keep on making the same engines you always have.
They already had a lead in battery-powered hybrids. It would have made so much more sense to lean into that, first into plugin hybrids and then plugin-only.
Hydrogen is such an obvious dead end, and everybody sees it but them -- the ones who should have been the first to figure it out. I just don't get it.
