Hydrogen cannot compete with BEVs for passenger cars. This will never ever change, because the problem isn't even current technology, the problem is physics.

Even putting that aside for a moment, there's a reason why VW and Mercedes cancelled hydrogen R&D the second batteries became dense enough for usable car range.

There's a reason BMW, once extremely anti-EV and pro-hydrogen has now switched. There's a reason why Toyota's new CEO is distancing the company from the absolute failures their hydrogen projects have been and have said they're getting into EVs.

BMW and Toyota were the two big pro-hydrogen carmakers, and they're abandoning it.

I don't want my reply to be a massive wall of text, so my issues with the physics of hydrogen cars will be in another comment.
