How do you figure? Everyone who doesn't live in big cities has the ability to charge an EV overnight, or in half an hour when road tripping. Absolutely none of them live within hundreds of miles of hydrogen refueling station.
Unless you have a quick charge at your house, or live in an area with one, you're not getting 30min quick charge at all. I'm 50 miles from the capital city in my state and we don't have any quick charge stations here. Anywhere. You really seem to be underestimating the size of the USA.
