What about dirt or sand or some such? Can you starve an EV fire of oxygen that way? If you can, what about dump trucks on stand by with dirt and shovels?
I think this push for EVs is rotten. But it seems like manufacturers would need to be able to tell municipalities and owners what can be done when EVs catch fire.
The lithium chemistry, with H2O, provides it's own O2. Ambient O2 is irrelevant.
