4 mins in the video, owners complain not enough Hydrogen fueling stations due to not enough people using Hydrogen car, no demand no supply issue.

That doesn't sound like the failure of the technology itself but failure of adoption.

Yes, so I don't see what TS is getting at about Hydrogen car failure.

If all the oil runs out, you have no choice but to go with EV or hydrogen.

If all stations are EV, have fun queuing; if you can charge at home, you won't need stations then would you?

Your other option would be hydrogen, upgrade the logistics to refuel the stations, problem solved already.
