If the car accidentally drove into the water
The first reaction is to open the car door immediately before the water flows over it. Although there is pressure at this time, it will not reach its peak. And when the water was halfway through the door, it was the penultimate opportunity to open the door. However, if after this moment, you can't open the door even if you exhaust all your strength, then all you have to do is to save your energy and concentration of oxygen and wait for the water to fill the car and then open the door in a rush. If there is really no way to open the glass to escape, you must remember to turn on the lights in the car when the surroundings are not particularly remote. This can prompt the surrounding pedestrians and rescue teams to make it easier for them to find the location of the car and rescue as soon as possible.
