Then you are creating an imaginary set of problems for hydrogen. We already have hydrogen cars that can go 400 miles. The range problem is already a solved problem. Future innovations will improve this even further. We already have hydrogen drones and bikes too. So there is no problem scaling down. Not to mention SUVs make up nearly 80% of the market these days. You're basically inverting how the real world car market works.

As we run into the fundamental problems of batteries, such as needing charging stations everywhere, and very high powered ones if we want fast charging, it will eventually become obvious that no amount of advancements will solve some of those issues. We will want to look at alternative solutions.

And again, BEVs are not competitive right now. They are a artificial market propped up by governments around the world. ICE cars still rule the world. And likely BEVs will retreat in the market as subsidy reductions and trade wars make them even less uncompetitive.
