Dead pedals have never been a required addition to standard automobile pedal sets. This is because the advantages of having a dead pedal are most commonly associated with manual transmission cars. Furthermore, cars with left side drive often have a natural footrest because of the wheel well so it is more common to find the right-side drive cars with dead pedals. However, the dead pedal promotes safe driving habits by serving as a place for drivers to place their foot and prevent accidental left foot braking. It is not recommended to brake with the left foot because it is less confusing when switching between automatic and manual transmission cars. Resting one's foot on the brake pedal may also accidentally light up the brake lights when the vehicle is not decelerating.
