I said time will tell. The infrastructure would cost many, many billions. If you use centralized h2 manufacturing, you'll be transporting how many hundreds of millions of cubic feet of h2 on the highway every day? Safe storage is also an interesting issue. Perhaps on-site/on-demand production at filling stations would be better, but the initial capital investment for the filling station owners would be huge. Mom-and-pop filling stations wouldn't be able to do it. HOWEVER, if some new technology comes along, making either the on-site/on-demand production cheap and easy or eliminate the safety issues with transport and storage, then I can see it happening. And I'd have no qualms about driving an H2 car.
