lithium batteries in cars (mostly due to MVAs) as well as bikes, scooters, skate boards and computers are also problematic when paired with cheap replacement chargers without good BMS's. All result in fires that are pretty much unextinguishable.
Tesla is the best with it's coolant acting as an extinguishing agent, however the consensus is to protect exposures and let them burn. It takes tens of thousands of gallons to stop thermal runaway in car batteries, and if you're successful the car should be towed to a quarantine area to sit for 3 weeks before any attempt at scrapping the battery is made.
We've already had a problem with a college student trying to recharge one of those green scooters vice leaving it out for the company to recover and recharge. His charger's BMS wasn't up to the challenge and it overcharged into thermal run-away. I understand that FDNY responds to multiple of these a day.
I was just at a structure fire caused by a cheap computer charger. Some form of regulation is needed.
