A salt water immersion is certain death. Worse is to not understand how it all goes down, and when the water recedes you try to start it. I Did not see it but I got an eye-witness account of a fellow who tried just that down on the Outer Banks. Out there most houses are up on pilings to avoid the flooding that routinely happens. The space under the house is a very convenient, and pretty much free carport. So the guy who tried to start his ocean-soaked car after the water went down not only burned up his car, but his house too. The fire departmenst out there on the Banks can be very far away.
