As cars become submerged underwater in a crash and the as people don’t know how to escape, lots of people drown each year. So, this is something that definitely wants to change.
This is a much complicated work. According to Geoff Fahringer, an expert diver, there is not enough time for rescuers to reach you in such situation, so you need to save yourself anyhow. You can only escape in the small amount of time you before the vehicle becomes completely submerged.
Calling for help won’t do anything, if you’re still trapped inside the vehicle. But, this is something people do quite commonly, even if it doesn’t do any good to you. Fahringer demonstrates how to escape from a sinking vehicle in the video below.
