People also seem to forget that petrol is dangerous stuff to handle and
yet we do that without a thought these days. At least if you "spill"
hydrogen it does not form ground dwelling puddle of highly flammable
vapour.

the Hindenburg disaster being often quoted.

ISTR a former NASA hydrogen specialist wrote a book on that:

Quite.

I noted this short paragraph: "He ... even reconfigured a white 1992
Ford Crown Victoria to run on natural gas and hydrogen. He derives
hydrogen for the car from water in his garage."

I think many of the current H refuelling stations run by ITM use local
electrolysis of water to generate their fuel stock locally. They appear
to have containerised their plant so you just feed it electricity and
water.

So in the future our cars could either be powered by electric motors
and batteries or ICE's and hydrogen, both recharged in our garages.

You will get significantly better efficiency from the fuel cell option,
although as a way of keeping classic cars running it might be worth it.
(also there is the problem of whether you can burn the hydrogen cleanly
enough in a traditional ICE)
