How long does it take for a car to fill with water when submerged?

[DiLeonardo]

It depends on the water level. Generally, if the water exceeds the height of the car, it will take about half an hour to fill up. Below is relevant information: Stay calm: If a car accidentally falls into water, many people panic, especially female drivers who may not know what to do and start screaming in the car. While such a reaction is instinctive, it's important to think clearly—panicking and screaming won't help. In fact, it often worsens the situation, causing confusion and making it harder to recall proper emergency measures. The most useful and fundamental action in this scenario is to stay as calm as possible. Take emergency measures: When a car is submerged, the pressure difference between the inside and outside makes it difficult to open the door. If the car hasn't been submerged too deeply, you might still be able to open the door and escape quickly. If the door cannot be opened, the only option is to break the window. When breaking the window, aim for one of its corners—avoid hitting the center, as it is the most difficult part to break due to the force being absorbed by the glass's vibrations.
