I drove 1800 miles in a Hydrogen Car

You should have let your viewers vote for the route you would take as a test of hydrogen infrastructure and availability (with transparent sourcing showing total energy used for the supply at a given location, also). 😊  We are just starting to get to where that isn't much concern for Tesla drivers anywhere in the country, let alone becoming hydrogen-fueling dependent. I had some exposure to Honda's work in this area. The total considerations, from total embodied energy use to production and refueling infrastructure, all costs relative to the benefits, just haven't been that appealing.
