Is it okay to park an automatic car without shifting to P gear?

[OJoy]

Automatic cars must be shifted to P gear when parking. The correct steps and precautions for parking a car are as follows: Correct steps for parking a car: First, use the foot brake to stop the vehicle, then shift the gear from D to N, engage the handbrake, release the foot brake, and turn off the engine. Then, press the foot brake again, shift the gear from N to P, release the foot brake, and turn off the power to remove the key. This is the safest and most reliable parking method. Although it may sound complicated, it is the least harmful to the car. Precautions for parking: Do not turn off the power immediately after stopping the engine. The purpose is to confirm whether the vehicle is completely stationary under the handbrake condition; otherwise, accidents may occur.
