Please define "usable battery life". For you crippled downto 1/3 of initial "factory range" could be possibly OK, but for me - rather not. Disclaimer: I do not say that after 1000000 km tesla battery has 1/3 range capacity. This is rather question what remaining capacity % of tesla battery after 1000000 km is.

Here is nice picture

So even after 1000000 km should be about 2/3 of the original capacity
That is still a reasonable range to use
And no issue when used as a second car

Currently car comes in, fills tank, gone in a couple of minutes. Once that flow is slowed down, there's a limit to how many cars can be hanging around, so throughput is going to be much lower and the filling station would need to make more profit per car (ignoring that more stations would be needed to maintain overall filling rates).

It the area a filling station takes, you can install many times more charging stalls. Which are also much cheaper. So throughput is not really an issue. For example, here you could easily install 20-30 charging stalls:

I spotted that many of the gas stations around me start to install one or two charging spots
So you can stop for the charge, get some snacks and coffee and in 30 minutes go on

They have been promoting the hydrogen nonsense for tens of years.
See: https://onlinelibrary.wiley.com/doi/10.1002/ese3.956:

--- Quote ---Hydrogen is often viewed as an important energy carrier in a future decarbonized world. Currently, most hydrogen is produced by steam reforming of methane in natural gas (“gray hydrogen”), with high carbon dioxide emissions. Increasingly, many propose using carbon capture and storage to reduce these emissions, producing so-called “blue hydrogen,” frequently promoted as low emissions. We undertake the first effort in a peer-reviewed paper to examine the lifecycle greenhouse gas emissions of blue hydrogen accounting for emissions of both carbon dioxide and unburned fugitive methane. Far from being low carbon, greenhouse gas emissions from the production of blue hydrogen are quite high, particularly due to the release of fugitive methane.

Regarding the magnet free motor I was referring to:

Regarding Na-ion batteries:

Biofuels already made lots of damage leading to deforestation and food price increase. Burning hydrogen in IC engines is just the last fashion in that greenwashing madness.

and there is plenty of room for solar panels  :)
