For powering vehicles, two infrastructures are currently in place: the
electric grid and hydrocarbon transport. It is through these channels that
we'll be powering our vehicles. I can't imagine building a hydrogen
infrastructure just to burn hydrogen in an internal combustion engine.

What I think will happen is that vehicle power sources will become more
heterogeneous, moving away from primarily gasoline/diesel to including more
hybrids and electric battery models. Anyway, this is the progression that I
think will happen. Sorry that I didn't answer each point you asked about.
