What is the primary way to control your speed in a vehicle?

The primary way to control your speed in a vehicle is through the braking effect of the engine. This technique, often referred to as "engine braking," involves using the engine's resistance to slow down the vehicle. When you shift to a lower gear or simply ease off the accelerator, the engine's RPMs decrease, which creates a natural deceleration effect. This method helps to maintain better control of the vehicle's speed, particularly when going downhill or navigating curves, as it reduces the reliance on the brake system and can help prolong the life of the brake components.

Using the brake pedal is also a common way to reduce speed, but it can create wear and overheating of the brake system if relied upon exclusively. Steering adjustments and accelerating gradually do not primarily serve as methods for controlling speed in the way that engine braking does. While these actions may assist in overall vehicle control and safety, they do not directly address the fundamental need to slow down the vehicle effectively.
