Not really true, you have a problem of toxic gases being released.[1] For my latest safety training in the maritime industry the handling of lithium battery fires was essentially put yourself upwind and let it burn it self out to prevent any exposure.
The conclusion from the paper is important:
"Using water mist resulted in a temporarily increased production rate of HF but the application of water mist had no significant effect on the total amount of released HF."
Though presumably, submerging the car would help by solving the fumes in the water creating hydroflouric acid instead.

- rightbyte 7y agoWhen I did safety training at a US Energy Department facility they said you should use salt extinguishers for lithium battery fires. They are quite rare and yellow. They didn't say why.
- marcinzm 7y agoThe study makes a note that it's testing HF production and not testing putting out a fire. "The intention in this study was however not to extinguish the fire completely." If you have the luxury of isolating the burning component and a lot of open space and a consistent wind direction you can let it burn. Few places outside of ships and desolate areas have that. Airplanes definitely don't. Neither do locations inside of cities. Cars also have many lithium cells so isolating the burning one is impossible and you probably want to avoid all of them catching on fire. Letting a car fire burn on it's own means you now have clouds of HF and you need to evacuate massive area for a long time. Or you drop it in water and avoid all that.
