Until technology is easily accessible to power vehicles on something like hydrogen, which I believe is the answer, given that it's freaking everywhere, and you can even extract it yourself out of the air with some Grade 9 Science, we will continue to be subject to the aforementioned bullsh1t.
It takes more energy to extract/separate hydrogen than you get in return. Simple laws of conservation of energy and inefficiencies. How can you start with water, end with water, and somehow extract energy in between? It's bunk.
