Ok, so now you go and tell all the car manufacturers to create hydrogen fuel cell conversion kits for ICE cars. I'll wait here for 50 years while they figure it out.

I've been with dealerships since 2005. It's not a plausible scenario. We can't even get regular maintenance parts.

Ask these manufacturers if they want to pay to hold classes on tech training for this ABSOLUTELY MASSIVE undertaking you've suggested.

Then, convert all the gas station infrastructure to dispense hydrogen.

Bad faith argument? It's literally easier to just make EV's or make cars that are DESIGNED to run on hydrogen. This is the real world where progress must fight against stubbornness. Your idea looks great on paper but that's it.
