That’s not true. A hydrogen gas station needs to be under a high pressure to be able to fill up just one car.

Ever heard of pumps? You do realize pump can build up pressure from lower pressure container? Even if the time needed to fill the tank is the same as EV you'd still get higher mileage per joule of energy simply by not having 700kg battery onboard.

That pressure is gone after 4 or 5 cars. After which it’ll take 45 minutes to build up pressure again.

Not sure where you got these numbers from but pretty much none of them make sense. I'd love to see some sources on that.

Simply stated, per mile or km driven it’s significantly cheaper to “fill up” an EV vs hydrogen. That’s due inefficiencies around hydrogen.

Completely pointless comparison. You are comparing centuries of battery evolution to a technology that started being developed recently. Per whatever price is not comparable. If you want to go that direction, then bicycle is cheapest followed by a public transport and gasoline. This is not a question about price, this is question of finding a solution that's scalable enough to replace gasoline, and batteries are not that. Lithium is rare enough, batteries weigh a ton and lose performance in the winter. They also take time to charge. Time which you can't reduce without affecting battery life. Not to mention excess weight wearing down roads faster, wearing down tires. All that affects environment.

To make matters worse, Toyota has released its newest engine which can run on hydrogen, methane and gasoline. Making transition very easy. Sure hydrogen production is expensive at this point, but prices will drop once there's competition and new greener ways are found to produce it. But change can start happening now. And by the way, am not talking about hydrogen EVs, but hydrogen ICEs.
