Where are the accelerator and brake located in an automatic transmission car?

The accelerator and brake in an automatic transmission car are located below the main driver's console, with the accelerator on the far right and the brake to its left, both controlled by the right foot. In emergency situations, if a person's feet are placed on both the brake and accelerator, there's a high chance of making a wrong judgment, such as mistaking the accelerator for the brake. Assigning control of both pedals to one foot reduces this possibility and also decreases the vehicle's side-slip coefficient when braking while pressing the accelerator. To prevent mistakenly pressing the accelerator instead of the brake, besides maintaining high attention while driving, it's essential to keep the right foot on the brake pedal when acceleration is not needed, regardless of the situation. This practice, known as 'preparing to brake,' allows for immediate braking action when needed, resulting in shorter braking reaction times and eliminating the risk of pressing the wrong pedal.
As an ordinary driver with several years of experience driving automatic transmission cars, I always locate the pedal positions as soon as I get in the car. On the floor in front of the driver's seat, the brake pedal is on the far left, with the accelerator pedal immediately adjacent to its right. My driving instructor emphasized this point when I first learned to drive, as it's a standard design that eliminates the additional clutch pedal found in manual transmission cars. I remember worrying about pressing the wrong pedal initially, but muscle memory develops with habit. The right foot controls both pedals, with the heel resting on the floor, allowing the toes to easily switch between the accelerator and brake; the left position is further left to allow the left foot to rest, requiring only the right leg to move when braking. This setup enhances safety, especially enabling quick reactions in emergencies. On long drives, you might notice the accelerator is slightly smaller than the brake, creating a different feel underfoot to prevent confusion. Of course, the positions are fairly consistent across modern vehicles, whether SUVs or sedans, adhering to a unified standard based on user habits.
Chatting with my mechanic friend, he mentioned how clever the pedal layout in automatic transmission cars is. Under the driver's side floor, the brake pedal is fixed on the left—usually wider to allow for firm braking pressure. The accelerator pedal sits snugly on the right, narrower in shape for gentle acceleration. Why? Automotive engineers designed it this way so the right foot naturally handles all acceleration and deceleration, avoiding left-foot idleness while maintaining overall balance. If you're modifying your car, never alter the pedal positions—it could create safety hazards. A common mistake among new drivers is wearing improper footwear like thick boots, which may get stuck on pedals. During practice, sitting upright helps build proper habits. The placement isn't arbitrary; it follows global safety standards to minimize collision risks.
