Hydrogen makes sense for semi-trucks and cargo transport - which are incidentally responsible for a huge chuck of ICE emissions.
That means even if we can't quite build out the infrastructure for civilian use, and the fuel cells are too expensive for the average Joe, we can still convert semi trucks to hydrogen use.
Even there, battery electric trucks are already selling in just about every weight class of trucks you can name. Hydrogen is a very long shot there and the (very) few hydrogen trucks on the road have neither range nor cost advantages over battery electric. And of course they can't go out of range from the very limited hydrogen distribution points.
