What is coasting in neutral while driving?

[AsherRose]

Coasting in neutral while driving refers to the operation method where the driver shifts the gear lever into the neutral position during vehicle movement, disengaging the clutch between the engine and the drive wheels, allowing the vehicle to move by inertia. Coasting in neutral can easily cause the engine to stall and may damage the car's engine. This practice should only be performed when safety is ensured and the vehicle's technical condition is normal. It is not recommended to stall the engine or coast in neutral when going down steep or long slopes. After shifting to neutral, the engine operates at a fixed idle fuel consumption rate; without disengaging, additional throttle input is required, and mismatched speed and gear may cause the vehicle to shake or stall. Modern vehicles are equipped with electronic fuel injection systems, where the fuel injection amount is controlled by an onboard computer based on sensors within the engine, making the idle speed non-adjustable in such vehicles.
