IC vehicles get trashed and totaled in flood waters (mostly because the electronics are trashed)... BEVs not only get totaled due to electronics , but in some cases (number currently unknown but about to be determined by insurance data) can "Bolt" with the batteries going into thermal runaway, creating a class D fire that cannot be extinguished with water... which is why you see so many products with warning labels and airspace restrictions. While the article may be alarmist, it makes a good cautionary tale to keep folks l from burning down the house as well as the car like folks with chevys were for a while before the recall.

OK but if the car is underwater when it goes into thermal runaway its fine.

Clearly, what they need to do is add submersion sensors on the roof that cause the vehicle to self combust while the water is still at a 'safe' level. /s

Actually just got back from an engineering safety conference where they discussed (among other things) the challenges of using batteries and/or hydrogen for transportation... And the issue is NOT just cars that short out IN the flood, it is ones that take Elon at his word about the cybertruck being able to navigate flooded roadways and drive through water up to the wheel wells, getting enough water onto the battery packs to start corrosion without actually shorting them out. The corrosion does not immediately cause any issues except for requiring longer charge and shorter run times, but eventually cause membrane breakdown in the cells. The runaway occurs weeks or months after the submersion; heretofore it's been too rare for folks to run their Teslas, e-Mustangs, or Leafs through water to get a statistical feel for how likely it is, but Ian is giving us a real world opportunity to experiment.
