Not a chance this catches on. People will fall into 1 of two camps in the next 20 years:
Gas powered because of nastalgia.
Electric because of performance.
Hydrogen is a useless middle-ground that requires new infrastructure for no reason. Gas is simple and we are used to it. Electric is even more simple and offers incredible performance. Hydrogen is just in between in that it's not as good as electric and also requiress insane investment and where the hell am I getting these fuel cells from anyway?
It is a way to preserve ICE cars without producing CO₂. People overstate the performance aspect of BEVs. Not many people actually want massive HP numbers without any mechanical drama. Not to mention that weight kills track performance. There's a reason why formula E isn't that popular. Fuel cells are for more practical minded vehicles. BEVs are also unsustainable will be replaced by hydrogen powered cars. It is pretty an inevitability. Too many people have swallowed BEV propaganda and not realized that BEV simply aren't going to scale, and are not much different than biofuels.
