How to Correct Steering When Turning Too Late in Reverse Parking?

The mnemonic for correcting early or late steering in reverse parking is: if you steer too early and the right side is narrow, turn the wheel back to the left; if you steer too late and the left side is narrow, keep the wheel turned fully to the right. Additionally, use the clutch to control the speed effectively. Only when the speed is sufficiently low will you have enough time to make corrections. When checking the rearview mirror, you don't necessarily need to sit up straight. Slightly leaning your head forward can help ensure an accurate view of the car's position relative to the parking spot corner in the mirror.
