Hydrogen also sucks in that it puts you in your own scaling lane. Relying on batteries means EVs, grid storage, et cetera drive down your costs for “free”.

Bertha Benz faced a similar problem in 1888, and had to refuel the Patent-Motorwagen by seeking out pharmacies. Drivers of the steam cars that were popular in France could just pick up a bag of coal from anywhere. (Wait, that doesn't sound right. A bottle of kerosene, then.)
