You're downplaying the efforts involved in making hydrogen mainstream. Hydrogen infrastructure would be more costly to build out because you need specialized tanks and mechanisms to pressurize/liquefy hydrogen to make it easier to store. You'd also need to convert gas stations to hydrogen stations which is very costly. Hydrogen fuel stations can't serve as many vehicles as a petrol station at a time and hydrogen being less dense means needing a much bigger tank to serve a day's worth of vehicles. Then there's the matter of generating hydrogen. Most productive processes now not are green.
The money poured into improved batteries has many applications other than vehicles. Hydrogen doesn't have as many consumer applications. It's not necessarily true that more investment in hydrogen would solve its problems because there may be roadblocks you're not anticipating. Battery tech is improving all the time, but you're calling it misdirection even though hydrogen isn't anywhere near as viable. Water is more available than petrol, but that doesn't mean hydrogen is more practical than petrol.
At the end of the day, you are just turning sunlight/wind and water into a fuel. The marginal cost is nearly zero. Which is why the development trajectory will be the same as the rise of wind and solar energy. Both of those ideas also had nearly zero marginal cost. As a result, you can expect hydrogen fuel to be extreme cheap and basically inexhaustible. That is a major advantage and there is nothing batteries can ever do to match that.
I wonder if you are projecting here: Hydrogen, not batteries, have many more applications. You can't even make the steel used to make a car without a reducing agent like hydrogen. Same is true of the metals in the battery itself. So if we want to hit zero emissions for real, hydrogen is mandatory, but batteries are not. In fact, BEVs are totally dependent on green hydrogen to real reach zero emissions. Everything from industry to long-duration energy storage all requires hydrogen. You can skip BEVs altogether but you cannot avoid hydrogen.
