What is the pedal on the far right of a car?

[LawsonRose]

The far right pedal is the accelerator pedal, also known as the throttle pedal, used to control the vehicle's speed. It regulates the amount of air entering the engine cylinders. Pressing the accelerator increases the engine's RPM and power output, while releasing it reduces engine speed and power. The far left pedal is the clutch pedal, exclusive to manual transmissions. The weight and height of the clutch pedal vary across different car models, resulting in different driving feels. Most modern clutches use hydraulic assistance. If air enters the hydraulic system, it can cause incomplete clutch disengagement and difficulty shifting gears, which translates to a soft or spongy clutch pedal with a sense of emptiness when pressed. The middle pedal is the brake pedal, which serves to slow down or stop the car. The sensitivity and travel distance of the brake pedal differ among car models, depending on the manufacturer's tuning.
