But this is the one of many issues, due to you needing to replace big chunks of your cars on regular basis, like every 5 years or so, costs of owning cars like that will simply be too high for regular people, on top of you needed to constantly recycle (duno how much you could actually recycle those tanks) and remake one. I mean, its good business for car manufacturer as everyone will be basically paying subscription fee to keep driving their cars, not that fun for customer.
At the moment coating with ceramics helps out to minimize hydrogen embrittlement, but even then, those expiration dates are already with top notch protections, so it's not like you could buy one from Wish and expect it to last.
And just FYI currently majority of hydrogen is being produced from natural gas, as its cheaper than to make it from water. Try to guess if this helps out with co2 offsetting...
Is hydrogen better than petrol/diesel cars? Yea, from the standpoint of it being cleaner. Is it better for customer? No. Even BEV's are cleaner when it comes to co2 footprint from end to end, not by much, but still cleaner and avoids majority of the issues relating to hydrogen cars. This is why 99.9% of all hydrogen car promoting people will try to sell it on the point that it refuels in only 5 minutes... Like that really matters when you can recharge from any wall socket...
We have alternative, its BEV's, trying to shift towards a worse option just makes no sense. While we need to transition to renewables, hydrogen isint the solution.

Full battery technologies, BEV's. Those keep improving constantly without any real limit on sight. While initial cost might be higher, what it offers can and does usually offset that over few years of usage. And transition to BEV's is really simple for the customer, you could basically just charge your car at home over night and never ever visit recharging station, you could even charge it from your own solar panels.
Its the most efficient way to move you from point A to point B. Like if you tried to compare energy usage between BEV and Hydrogen car, you will need around 60% more for hydrogen car to travel same distance due to the fact that you need to convert energy into hydrogen and then hydrogen back into energy, which will have huge amounts of energy loss in that process.
Where hydrogen could work out is bigger things, like ships, planes, trains, semi's and so on, which could have their own refueling stations with their own team of people which keeps them running at relatively low costs due to it being done in house, but hydrogen will never work for regular passenger cars.

"Can we sustain the mining operations required for EV growth?"
Yes.
"'Can we fix the e-waste issues unrecycled batteries create?"
Yes. Batteries are being recycled and in general you can recycle like 95% or even more of the old battery and reuse materials for the new ones. What is ironic at the moments is that there isn't enough old BEV batteries to be recycled yet as those lasted longer than expected, so not many recycling plants have been built, as there isn't batteries to be recycled in mass, yet.
"Can EVs manage to improve in the secondary market where values drop almost 10 times as fast as ICE cars and buyer confidence appears to be dropping faster than the used cars' prices?"
Example Depreciation Curves
BEV:
Year 1: -25%
Year 2: -20%
Year 3: -15%
Year 4: -10%
Year 5: -8%
Year 6+: Gradual decline influenced by battery health and market trends.
ICE:
Year 1: -20%
Year 2: -15%
Year 3: -12%
Year 4: -10%
Year 5: -8%
Year 6+: Steady decline based on age, mileage, and condition.
Doesn't look like there is your 10x anywhere.
"Just like it will tell buyers if EV ranges will ever reach the numbers 'promised' 10 years ago."
Which would be what? How much do you want and how much to you actually need? And there is BEV with 500 mile range, so how much more do you need?
"same coal fired grid"
How is that even related? Grid is being shifted towards renewables, majority of electricity should be coming from renewables, just because there are still few coal ones will not really impact anything here. At the end of the day its still cleaner option than ICE cars.
"You can't paste luxury sport packages over real world problems and call it progress."
EVERYTHING was a luxury at the start. Look t first LCD tv's, 13 inches for 4000 bucks, now you can get one for like 100 bucks with better quality. We got real BEV's like a decade ago, which is still quite new technology as no one wanted to invest billions into R&D without knowing that it will pay off, but look at all new battery technologies being presented now from dozens of companies. We even have carbon nanotube batteries which are exponentially better, issue is just with production scalability which needs to be solved and if it is then that's that.
There isint perfect solution here, every single technology has its own drawbacks, but at the moment BEV's at he best option we have and simplest one to transition into. As a reminder, we have over 3 000 000 BEV charging stations, while there are under 1000 hydrogen ones in entire world. This excludes the fact that you can charge your car at home, so people outside cities and living in their private homes could avoid visiting charging stations entirely, they can even charge their cars with few solar panels...
