Because hydrogen for cars makes no sense. It's all made from natural gas (and if we produce it from water, it would take at least thrice more energy than what's needed to charge the same energy in a battery... at best), it's more expensive, it's far more dangerous, the infrastructure is not there (and never will, you can't put a hydrogen station in every garage), etc. It only makes sense for chemicals, stell production, fertilizers, seasonal energy storage, and long distance transportation (search images for "hydrogen ladder"). But the O&G industry bet big on hydrogen a long time ago, and got a few auto giants like Toyota to jump in. It was a bad choice (but who could oppose the energy leaders back then?) and it's too late now.
