This is well worth a watch - summarises just how ridiculous hydrogen combustion is for powering vehicles!

The answer is clearly, park your sh1t car by celebs, (the non smoking variety) not Robert Downey jr.

Dan, if you haven't already, it's also worth watching his vid on Toyota's HICE. As he points out, it's the volume of the fuel tanks that are needed, that are the main problem. They'd fill the whole vehicle.
Also watched several vids on H2 and discussions around its use, and they all seem to require the H2 being produced near to where it's used, as transportation is a pain. Only my questionable research, but a large H2 tube trailer can carry about 600kg of H2, roughly equal to about 600 gallons of petrol (in that V12 engine, or one of JCB's heavy plant HICEV's). So you need about 10-12 tube trailers to move the same energy as one petrol tanker.
"Merica" ..I s'pose.
Marketing vs common sense too.
Yet if that really were the case then surely itty bitty bmw mini 's would never have eneted the marketplace o'er there.

Mart, what's that in road / equivilent tanker space taken on a congested road?
A regular tanker is a 40 footer I presume?

The "Hydrogen is just around the corner" myth is perpetuated by FF companies as an excuse for doing nothing. It is lies, "fake news", and disinformation.
BEVs are here. The grid is a fantastic way to transmit energy.

Deutschland, the land of no speed limits. Feels strange being overtaken when you are doing 255kmh!

He did another video a while back showing how difficult it was running hydrogen in a FF engine.

I’ve just remembered: I got kicked off the old forum for a few weeks of explaining that “the the only product of burning Hydrogen in an ICE is water” is a completely false statement! It turns out one of the “mods” owned a hydrogen burning ICEV and didn’t want the truth to see daylight!
