In an automatic transmission vehicle, the accelerator is located on the right side, positioned in front of the central armrest on the right-hand side, making it immediately visible upon entering the car. The primary reason for this design is the frequent use of the accelerator, which is placed on the outer side of the right foot for a more comfortable posture. The brake is set on the inner side of the right foot, with the brake pedal slightly higher than the accelerator pedal to facilitate quick reactions from the driver. The correct operation method involves pivoting the right heel and using the ball of the foot to press the pedals. The accelerator position is controlled by the driver in the cockpit through the throttle lever, which transmits commands via linkage systems such as rods, rockers, torque tubes, cables, pulleys, and sector gears to the carburetor or fuel regulator on the engine.

I remember when driving an automatic car, the pedal on the right is indeed the accelerator, which is designed very reasonably, making it more natural for the right foot to control acceleration. As a driver with years of experience, once accustomed, the operation becomes particularly smooth, unlike manual transmissions where you have to divide attention to press the clutch. When starting the car normally, a gentle press on the right accelerator allows for a smooth take-off; during high-speed driving, maintaining a steady accelerator is also crucial. But I must remind myself to promptly switch to the left brake pedal in emergencies, and not to confuse by placing both feet on the pedals. The key to safe driving is the right foot being responsible for switching between the accelerator and brake, with the left foot completely still. It's recommended for beginners to practice more with low-speed driving in garages to get a feel for the coordination between the accelerator and brake, and they'll get the hang of it gradually.

When I was learning to drive as a beginner, I initially struggled with the pedal positions of an automatic transmission. But after repeated instruction from my coach, I finally understood that the right pedal is the accelerator and the left one is the brake. From being so nervous during my first drive that my palms were sweaty, to now operating with ease, practice truly makes perfect. When driving, pressing the accelerator with my right foot to speed up feels particularly intuitive, eliminating the distraction of gear shifting found in manual transmissions. Regarding safety, I always remind myself to avoid impulsive acceleration, especially in parking lots or during rainy days when the roads are slippery. As a daily commuter, this design makes city driving more worry-free and even extends to features like cruise control for long-distance travel. With more road experience, the accelerator position becomes muscle memory, ensuring no mistakes are made.

When I was a driving instructor teaching students how to drive automatic transmission cars, I always emphasized that the right pedal is the accelerator and must not be confused with the left brake pedal. Using a real car for demonstration, I had students focus their right foot on controlling these two pedals: press the accelerator gently to accelerate, and lift lightly when switching to the brake. The design principle aims to reduce accident risks, such as preventing beginners from mistakenly pressing with their left foot. In practical operation, repeated practice of starting and stopping in the garage, as well as accelerating during turns, helps students naturally adapt. An extended safety recommendation is to maintain proper seat adjustment to ensure natural foot movement. Once the habit is formed, safe driving becomes much easier.

I've studied automotive engineering, and there's scientific reasoning behind placing the automatic transmission's accelerator pedal on the right: ergonomically, the right foot has greater strength, allowing for precise control of acceleration force, while keeping the left-side brake independent to minimize misapplication. Compared to manual transmissions where the clutch occupies the left side, automatic transmissions simplify operations for more comfortable driving. In daily use, the right-side accelerator ensures smooth responsiveness and reduces foot fatigue during urban traffic congestion. Safety-wise, the design accounts for emergency turns or slippery conditions like rain/snow – single-foot control with the right enables quicker reactions. Regular inspection of pedal wear is recommended to maintain responsiveness.
