I can believe I would see so many idiotic comments. Yeah right try to push a ton of water out of the way, and hold your breath at the same time... remember next time you go to swimming, bring a surfing board (much smaller than a car door), dive in and try to push it under the water and see how many inches you can get. - U would be lucky if u are not getting pushed back! We really don't know much about water, and it's no coincidence that we chinese is never a nation w/ rich tradition of sailing.
The only chance for this guy would be: when he saw water rising so quickly, get windows open fully as quickly as possible, beating the water before it gets to the battery and shut everything down, and then get the hell out from the window and get to the roof, and then...... wave for help!!!
my condolences to his family.
Brace yourself for impact. As soon as you're aware that you're going off the road and into a body of water, adopt a brace position. This is done by placing both hands on the steering wheel in the "ten and two" positions. The impact your car makes could set off the airbag system in your vehicle and any other brace position could cause serious injury in such an event. Remember, an airbag inflates rapidly, within 0.04 seconds upon being triggered.[3] Once this aspect is out of the way, prepare for the next step immediately.

Remain calm. Panic reduces energy, uses up precious air, and causes you to blank out. Repeat a mantra of what to do to get out (see next step) and stay focused on the situation at hand. Panic can be left for the shore when you reach it.

Undo your seat belt. Professor Dr Gordon Giesbrecht, who specializes in cold water immersion, says that the seatbelt is the first thing to attend to, yet it often gets forgotten in the panic.[4] [5] His motto is: Seat belt; children; window; OUT (S-C-W-O).
Unbuckle the children, starting with the oldest first (who can then help the others).[6]
Forget the cell phone call. Your car isn't going to wait for you to make the call and sadly, people have lost their lives trying this.[7] Get busy getting out.
There is a counter-theory that suggests the seat belt should be left on. This theory suggests that if you release your seat belt, you may, due to underwater disorientation, end up moving away from the window or door opening due to the ingress of water through the opening. If you need to push the door open, being anchored by the seat belt might give you additional leverage, versus pushing the door while you're suspended in the water.[8] Having your seat belt on could also help you maintain your sense of orientation if the car flips upside-down. On the downside, having your seat belt on can also make it harder to get out quickly and to move out, which is the point of reacting quickly from the start and not waiting in the vehicle. In the video featuring Rick Mercer and Professor Gisbrecht below, they show clearly that it's important to be able to move around from the start, including if you need to move to the backseat to get out of the car as the engine-heavy front part starts tipping deeper first.[9]

Open the window as soon as you hit the water. Following Professor Giesler's recommendation, leave the door alone at this stage and concentrate on the window. A car's electrical system should work for up to three minutes in water[10] (not that you have three minutes of course), so try the method of opening it electronically first. Many people don't think about the window as an escape option either because of panic, lack of using the window for exit normally, or because they're focused on lots of misinformation about doors and sinking.[11]
There are several reasons for not bothering with the door according to Professor Giesler. Immediately upon impact, you have only a few seconds in which opening the door of your sinking car is possible, while most of the door is still above water level. Once the car has started to sink, it is not humanly possible to open the door again until the pressure between the inside and the outside of the car has been equalized (leveled); this means that the car cabin has to be filled with water and that's not really a state you want to be in.[12][13] Moreover, Professor Giesler says that by opening the door, you invite a quick sink in place of the floating time available to get out. In his experiments with 30 vehicles, he found that all vehicles float, anywhere between 30 seconds to 2 minutes.[14] You could be using this float time to escape rather than opening the driver's side door and giving the water 5 to 10 seconds to sink the car and drown everyone in the backseat.[15]
There are numerous theories that advocate staying in the car calmly until it hits the bottom, fills with water, and you open the door and swim up. Mythbusters termed this the "maximum conservation of energy" approach and it looks viable when you watch it. The trouble with this theory (tested only in a swimming pool of known depth with a rescue crew on full standby) is that most times you won't know the depth of the water into which your car has plummeted, so waiting this long will usually prove fatal. This method worked just over 30 percent of the time in Professor Giesbrecht's study, while his S-C-W-O approach worked over 50 percent of the time.[16]
