I'd think on the "it would already have been done by now" point, car manufacturers aren't going to introduce ideas that mean extra work on the part of the driver, i.e. having an extra tank to top up. If they get it wrong, then bad things can happen and they would be held responsible!
Another thing I've found about many many mods here is that they are climate dependant. What works for one person in one part of the world may not work so well in another, you'd have to introduce antifreeze and anticorrosion agents and all sorts into the water to make it work on a production vehicle and the costs around such things, the potential headache in getting it working and the fact that not all buyers would be happy with it anyway means the auto manufacturers are not going to do it if it only gives small gains.
We, however, don't care about the hard work, and we don't care if it will break at -20 if we aren't in a cold climate etc. etc. We design things in specific ways to suit ourselves, and we also don't mind too much if the life of the engine is shortened because it doesnt necessarily have to last for hundreds of thousands of miles like this. We also don't care if it only gives us an extra 2 or 3mpg, because we're going for absolute max whereas the big brands only care about matching eachother and EPA targets which they can do by other means. That is why we can take advantage of so many things that the car makers cannot.
