The braking effect is greatest when near the governed RPMs and in lower gears because maintaining a lower gear allows for increased engine braking. This is a crucial aspect of driving that utilizes the vehicle's engine to slow it down without solely relying on the traditional brakes. When you shift to a lower gear, the engine is engaged more actively, and resistance from the engine helps to decelerate the vehicle as it decreases in speed. Driving near the governed RPMs means that the engine is operating at a high level of efficiency where it can provide maximum torque and resistance against forward motion. This, combined with the lower gear, enhances the overall braking effect, allowing for safer and more effective stopping, especially on downhill slopes or during sudden stops. In contrast, using a higher gear diminishes engine braking effectiveness, as the engine does not absorb energy as efficiently when a vehicle is in gear too high for the speed. The emergency brake alone is designed for emergency situations and does not provide the same level of controlled deceleration as engine braking in lower gears. Lastly, braking at high speeds generally requires more force and time to stop safely, making it less effective compared to the situation described.
