Why does the car move forward slowly when in N gear?

[CarterDella]

The reason why the car moves forward slowly when in N gear is that when the road is flat without resistance or has a slope, the vehicle will slide slowly due to inertia, which is caused by the structure of the car itself. Therefore, when waiting at a red light, you should wait until the vehicle comes to a complete stop before shifting to N gear, and then step on the brake or pull up the handbrake to prevent the car from moving forward. An automatic transmission usually refers to the car's automatic gear-shifting mechanism. When driving, the control system of the automatic transmission automatically selects the appropriate gear based on the engine speed and load, replacing the driver's subjective judgment of timing and gear-shifting operations. Generally, automatic transmission cars have six gear positions, from top to bottom: P, R, N, D, S, L.
