I drove 1800 miles in a Hydrogen Car

The real question is, "why aren't they making hydrogen combustion hybrids?"  You can split water molecules to create 2 hydrogen and 1 oxygen atoms.  You can, then, burn the hydrogen/oxygen combo in a modified internal combustion engine.  That engine, can then, be used to charge a battery as any other hybrid.  The only thing you need to keep replacing to fuel such vehicles is... WATER.
