I read just this morning how EVs are safe in floods and there is very little chance of being electrocuted, but be absolutely sure you don’t try to operate them, or plug them in, or leave them within 50 feet of a building or other cars in case the battery explodes, or get near them if you see bubbles because it probably poisonous gasses.
Sounds safe.
Not really worried about being electrocuted. However after some mileage if the battery casing cracks and water interacts with the lithium, there very well could be a fire.
