That's true, the BMW I read up on was just a research car. Concidering what a small quantity can do (a beaker full makes a pretty big explosion) It'd be a while before i got inside one. Plus, having a tank full of it might be pretty dangerous. Hydrogen fuel cells seem more viable and a more realistic use for hydrogen. I wouldn't expect to see hydrogen in internal combustion engines any time soon.
