Sealed car oxygen can be absorbed by an adult for 600 minutes. Oxygen content in a sealed car: Under safe conditions, the actual amount of oxygen available for normal breathing in the car is only 150 liters. If an adult breathes 20 times per minute, they will consume 250 milliliters (0.25 liters) of oxygen per minute. Carbon dioxide concentration must be considered in a sealed car with no air circulation: When the carbon dioxide concentration in the air exceeds 5%, a person will soon fall into a coma, and prolonged exposure to this state can lead to death. If the car environment is relatively sealed and lacks air circulation, the carbon dioxide concentration must be taken into account.

Should You Turn Off the Engine Before Shifting to P Gear or Shift to P Gear Before Turning Off the Engine?

It is best to turn off the engine before shifting to P gear. Engine shutdown method: Normally, when parking the car, first bring the car to a complete stop, then shift the gear to N gear, engage the handbrake, turn off the engine, and then shift to P gear. This is the correct way to turn off the engine. The correct steps for starting an automatic transmission car are: Press the brake, engage the handbrake, start the engine (do not directly shift to D gear; shift to N gear first and then start the engine, then shift from N gear to D gear), release the handbrake, release the foot brake, and release the handbrake (for electronic handbrakes, simply press the button briefly). You can choose to warm up the car in place, and the time can be determined based on the environment. Press the accelerator and start moving. Depending on the road conditions, press the accelerator smoothly to accelerate and drive safely.
