Faster refueling is definitely a big one but the refueling state for hydrogen is abysmal.

That’s after significant government and corporate funding.Toyota would need to be like Tesla and really bootstrap their refueling infrastructure for those people converting from gas but not going to EV, like you said.

I suspect most hydrogen drivers are more interested in the cost savings on gas/vehicle than the environmental impact. The verge did a special on hydrogen cars recently and every owner they talked to basically credited cost over any other factor.
