IIRC Toyota bet hard on hydrogen fuel cell technology and have been stubbornly working on making them a thing instead of pivoting to BEVs.

Which I’m not exactly mad about or sure if it is (or isn’t, I genuinely don’t know enough about the technology to make a call) a bad decision. While it’s certainly looking right now like BEVs are the way of the future, maybe Toyota will make some breakthrough and hydrogen really will end up being the next big thing.
