One of the YouTubers I watch, Tavarish, is rebuilding a flooded McClaren. McClaren went to great lengths to water proof the car (IIRC almost all the connectors for the electrical harness and many of the other cables/wires in the car were all fine). The car is an engineering marvel and it still had damage done to the battery and almost every inch of the car had water intrusion.

Not disagreeing with you but salt water tends to fuck shit up. Maybe a better solution is some kind of system with a series of sensors and other inputs that could disable the battery until it's checked out? Or maybe better education on how dangerous lithium batteries can be.

There's not much to disable unfortunately. Provde a short circuit path between the anonde and cathode and you're going to get thermal runaway. You could try inside the cell protection, but that's going to be pretty expensive given a Tesla containing thousands of smaller capacity cells. Other OEMs use larger "large format" pouches, but they still a have hundreds.

He does find some other worrisome things when going through that car.
