[McJordan]

When the car door cannot be opened due to the high water pressure, you should wait until the water almost fills the compartment before attempting to open the door or roll down the window to escape. Using sharp objects inside the car: If there are sharp objects inside the car, you can try to break the glass by striking the four corners of the window. Escape through the sunroof: Most cars are designed with a sunroof, which can be used to escape by opening it.

Escape through the window: After falling into water, if the vehicle's performance has not completely failed, you can use the window to escape.
