They aren't in production,
They aren't in production, only building prototypes. They plan to enter production in 2014-15.
Hydrazine can be produced in the same way hydrogen is produced. The nitrogen is all around us, all the time. It's a simple chemical process. Neither hydrogen nor hydrazine is produced from electrolysis, though - most comes from natural gas. And it will continue to be so for the foreseeable future because the other methods are not sustainable in production quantity.
Again, I pointed out the problems with hydrogen fuel cells in this article - problems which you've completely ignored in favor of claiming that H2 is "safe" - which it isn't.
You're bordering on religious zealotry here. This is an alternative that is cheaper to use, just as cheap to get, and that can go into production (in terms of automotive) much faster and at lower consumer costs than hydrogen fuel cells can.
