Oil doesn’t make self-oxidizing metal fires. You can easily put out an oil or gas fire with water and it will stay out once cooled off. You have to just let lithium batteries burn and even if you get them extinguished, there’s no where to store, transport, or recycle them safely because they reignite without warning at any temperature.

Yes, there are mitigations, but that doesn’t change how fundamentally dangerous they are. Gas tanks do not spontaneously ignite if punctured. Gas is easily cleaned up. Batteries become permanently unsafe and can catastrophically fail at any time with no warning.
