At what water level should a car not be driven when submerged?

[DeBradley]

A car should not be driven when water reaches the intake level. Below are the specific impacts of water entering the vehicle: Rust and corrosion of the vehicle: Once water enters the floor, it can cause corrosion to the floor and metal components, particularly accelerating rust on metal parts, leading to vehicle malfunctions and increasing risks for passengers. Vehicle wiring short circuits: There are numerous wiring lines under the vehicle's floor. If water enters, these lines may short-circuit, affecting normal vehicle operation and potentially damaging the onboard computer due to electrical faults. Vehicle odors: If the vehicle floor gets wet and is not promptly treated, the damp floor can easily mold and deteriorate, producing unpleasant odors inside the car.
