Yeah, that was a little too subtle. I had to check it a few times before I realized they weren't talking about hydrazine (toxic, probably carcinogenic if it doesn't kill you right away, and definitely not something you want putting around on public roads).

If I were their marketing, I'd pick something else, fast. Something a good hamming-distance away from anything requiring special suits for handling, and that doesn't include steps in release protocols like "evacuate nearby towns".
