Let's say Germany has a decent hydrogen infrastructure. You go on vacation in say Croatia or Spain, you suddenly can't use your car. Every country has electric sockets everywhere so you can charge over night and building fast chargers is trivial compared to storing hydrogen. Hydrogen sounds useful for commercial vehicles where you can plan routes and stay close to pumps (eg. delivery, bus, etc.) Sounds horrible for personal vehicles. I can see Japan investing in it - you are unlikely to travel out of country with your car.
