The only way I know how to reliably extinguish a lithium car battery fire, is to throw the whole car into a water tank

    That's two ways: if you can throw a whole car in a water tank, you can throw a whole water tank on a car.

    Nope. The moment you stop flooding it with water, it starts burning back again. Lithium reacts with water producing heat and hydrogen. Spraying the surface with hose just doesn't work. You have to drop car into a water tank for prolonged period of time. Long enough for water to reach all damaged cells and react with all exposed lithium
