BMW is in the R&D of hydrogen as a vehicle's fuel for more than 40 years now.

I think you need to remove one 'ICE' and put 'transmission' there for it to make any sense 😛. Wife's car is marketed as full hybrid as in toyota-speak parallel has the motor in series with the drive shaft to the gearbox. potato/potarto.
I'm old school. Anything without a clutch and stick is just transport. Which means the only REALLY interesting car in the current Toyota lineup is the GR Yaris. Sadly not sold in the USA as not much market for a road legal rally car.
The lack of manual transmission is causing me a lot of internal strife in going from ICE to any hybrid/electric/whatever. This is coming from a treehugger smfh.
Several makers have been interested in hydrogen for a long time but it never went anywhere. Metal hydrides with the hydrogen used in an ICE. Fuel cells have moved on since. There are claims that they are around 100% more efficient related to the calorific value of fossil fuels/ hydrogen used in an ICE.
😉 Subaru. I did run a wrx more recently a forester. For road use they corner at there best when a certain amount of power is applied through the corner. Rally style is a bit different.
Looking at more recent hybrid models ice engine driving a generator seems to be the best improvement so far. Makes sense as gears and transmissions etc are not very efficient.
Currently the UK Gov take ~£25b a year in fuel taxes. A lot to make up when and if conventional fuels aren't used.

I have a notion that future civilian air travel could function on an engine
that has dual fuel injection of Bio Deisel & Liquid Hydrogen.

A problem with hydrogen is that special materials and electrodes are needed, it is less stringent than radiation proof material, but costly in comparison to normal steel / plastic tanks.
Hydrogen can leak through tiny gaps, and affects metal lattices, it seems.
Storage devices for hydrogen using matrices have been studied for years, principle is same as dissolved acetylene cylinders.
Due to addition of ethanol to gasoline (here 10%, planned to 20%), plastic fuel tanks are almost compulsory, as alcohol can absorb moisture from plant to fuel tank.
As for land, well, look at Israeli farming techniques, they had to be frugal. Not an issue.
I use a car with an after market natural gas kit, 40% fuel cost saving, negligible particulate emissions or green house gases.
I think you may not need an expensive catalytic converter with those levels, if your vehicle is pure gas.
Mumbai and Delhi have more or less banned diesel trucks, so they all have gas conversions, and some long distance trucks have CNG and LNG as the fuel source.
And a friend just bought a 3 ton load class truck with CNG as the only fuel, spark ignition of course.
Says it costs him only 40% of diesel...

The VW PHEV comes close with it's adequate DSG gearbox, which also works when on battery only, not that you need to use it though.
My CRZ is a manual with motor assisted 1.5l i-Vtec petrol ICE. The 100v, 100amp (10kw) motor is about 75mm thick and sandwiched between the engine and clutch. It also starts the engine and provides all 12v power as there is no alternator.
Pfft, that's just copied off the Lohner-Porsche of circa 1900.

I worked on EV's ~35years ago. LOL They used 1tonne of lead acid batteries idea being to get the basic technology sorted and wait for a more suitable battery. A number of auto companies were doing similar work even on hybrid arrangements but technology has moved on so much it's doubtful if the work was of much use. The control was essentially analogue rather than digital, They used a chain drive for speed reduction and then a differential. Chain as it's the most efficient - till the chain stretches. Increasing electric motor speed tends to make them smaller but speed reduction is then needed. Be interesting to see if that ever goes.
Anyway Hyundai has come up with an idea that removes the need for the diff. It also gets around the known problems with in wheel motors - to some extent anyway. Will it work out and ever reach production - who knows really.

Hydrogen embrittlement and hot hydrogen attack were known issues, still there were bitter lessons to be learned with the Rockwell X-30 test bed during mid 80es in USA.
Sandia Labs issues updates on a list of hydrogen compatible materials

I passionately hope he succeeds. Australia deserves it - Yull Brown, brown’s gas....

Only 15 minutes to charge. Just have to wait an hour and a half in line first.

I didn’t go past the headline, but i would be interested in how if differs from the REE which is already shipping vehicles with everything in the wheel. https://ree.auto/

Hyudia make a point of getting rid of cv joints plus shafts and like REE do not use in wheel motors.
I didn't know they did the CR-Z with a stick. Interesting. Don't see many of that model on the road. I should note after 24 hours with a hybrid the wife has said she would happily never drive a manual again.
One more news, a Vietnamese cell phone maker is starting a plant to make EVs in India, they have good volumes in the Far East.
They are not the only ones, some Chinese companies who started making cell phones have added cars to their product range, in some cases by buying up bankrupt (or nearly so) car manufacturers.
They know batteries and drives, body / chassis was the obstacle, solved.
That is a looming threat for the existing car makers, who have bases in ICE technology, particularly those in the Stellantis group of car makers.
Electric 4x4, anybody?

There was a documentary on Chinese cars a while ago. A number of them had very familar looks and vaguely familiar names. Copies in other words. I'd wonder if buying up outfits like that would achieve much.
There have been many mergers like that in the past. That one is pretty big making it the 4th largest manufacturer. Time will tell in terms of it working out. Maybe the problem is that the individual parts are not large enough to compete with the big boys. Those are definite brands, Toyota, VW and Hyundai. It costs a hell of a lot of money to produce a new car these days. That's why mergers happen. Or a company like Ford selling some one else's car.
China. They have SAIC Motor, state owned. Their offerings currently in the uk are these

Their top EV

Price depends on range and trim. That is pretty aggressivity marketing. Interestingly the state range for various driving conditions. I have come across people who think this is constant on EV's down to the way range is often specified.
