Reports out of Naples indicate that flooded EV's are literally time bombs. and some have already caught fire.
Fresh water is not very conducive but salt water conducts electricity very well. Salt is soluble in water and divides into sodium ions which are positively charged, and chloride ions, which are negatively charged.
All sources of electricity, like batteries, have two terminals, a positive and a negative.
SO:
Batteries saturated in salt water, (even if somewhat dry), have this conducive material spreading the current, which sparks, and then catches adjacent material on fire.
Mark,
What is the view on this in storm ravaged Naples??
