Hydrogen cars are safe. They are designed so that, in the event of a tank puncture, the hydrogen will evaporate before it can do anything.
Also, it wasn’t the hydrogen that was the problem with the Hindenburg. It was the flammable paint they used on the dirigibles.

And the hydrogen blew up. The United States which pretty much had the monopoly on the less flammable helium was prohibiting sales of it to Nazi Germany because of it’s treatment of German Jews. I don’t want a hydrogen car. I’ll stick with gasoline. And besides you still need lubricating oil under the hood and that means petroleum.
“Also, it wasn’t the hydrogen that was the problem with the Hindenburg.”
Well, the hydrogen wasn’t the problem. It was the oxygen.
