Can the car window be opened if the car falls into water?

[SanBella]

No, opening the window would allow water to rush in, and failing to escape in time could lead to drowning. Additionally, the pressure difference between the inside and outside increases the friction between the glass and the window frame, making it very difficult to open the window. 1. Correct approach: When the water levels inside and outside the car are unequal, the car door cannot and should not be opened immediately. You must wait until the water levels inside and outside the car equalize before opening the door. It is also advisable to keep a window-breaking hammer inside the car for emergencies. 2. Principle: When a car falls into water and the water levels inside and outside are unequal—meaning the water level outside is higher than inside—the difference in water pressure between the inside and outside will create immense force, pressing the door shut. This makes it impossible to open the door. Even if you manage to open it, water from outside would immediately flood the car, trapping the occupants and causing the vehicle to sink rapidly.
