There is always one problem with batteries and cars - exploding. Batteries have the full chemical reaction ready to go all the time. Crush a battery and all of it's power can be released at once. Leaking fuel releases energy only as quickly as it can mix with air. Hydrogen creates an impressive fireball and gasoline melts bridges, but there's still a lot of slow heat dissipation into the air and there's always an option to smother the fire. Imagine that same energy being constrained to a small battery pack. There'd be a crater to fix after a bad crash.

I suspect that we'll continue using fuels for a very long time. Probably something more friendly to fuel cells than gasoline, but definitely an oxygen consuming fuel.
