Which letter represents the reverse gear?

The reverse gear is represented by the letter 'R', usually located between the 'P' gear (Parking gear) and 'N' gear (Neutral gear), designed to allow the car to move backward, serving as a special driving gear. Common automatic transmissions include P, N, S, D, R, and L gears. The working principle of an automatic transmission is to use planetary gear mechanisms for shifting, automatically adjusting gears based on the degree of throttle pedal pressure and changes in vehicle speed. The correct method to park an automatic transmission car is: 1. Press the brake to slow down to a stop; 2. Shift to 'N' gear after coming to a complete stop; 3. Engage the handbrake; 4. Release the foot brake and ensure the vehicle is stationary; 5. Press the foot brake again, shift to 'P' gear, and turn off the engine.
I've driven quite a few cars and noticed that the reverse gear is always marked with the letter R, which stands for Reverse in English. Every time I back into a parking space, I first press the brake pedal firmly, then shift the gear lever to the R position. At this point, the rearview mirror automatically tilts down, and the reversing camera lights up. Actually, the gear lever designs vary interestingly across different car models. For example, my SUV requires pressing an unlock button to engage reverse gear, while my friend's older sedan can shift directly. Besides the R gear, common automatic transmission positions include P for Park and D for Drive. Although manual transmissions also use the R symbol for reverse gear, you need to lift the ring at the base of the gear lever first. Remember, shifting into the wrong gear can be dangerous. Once on a rainy day, I shifted to R without coming to a complete stop, and the car suddenly lurched backward, nearly hitting a wall.
