Why is coasting considered a dangerous driving practice?

Coasting is considered a dangerous driving practice primarily because there is no engine braking involved. When a driver allows the vehicle to roll without engaging the gears, the engine is effectively disengaged from the wheels. This means that the vehicle cannot utilize the engine's braking power, which can significantly reduce the driver's control over the vehicle's speed and handling.

Without engine braking, the driver must rely solely on the brake system to control speed, which can lead to longer stopping distances and an increased risk of skidding, especially in adverse weather conditions. Additionally, coasting can make it more difficult to react quickly to dynamic driving situations, such as needing to accelerate to avoid a hazard or navigate through rough terrain. As a result, maintaining control through proper gear engagement is essential for safe driving.

The other options suggest benefits of coasting, such as fuel savings, avoiding speeding tickets, or enhancing acceleration, but in practice, these advantages do not outweigh the safety risks associated with reduced vehicle control.
