What is the reason for the car body crossing the line when reversing?

[ConnorFitz]

Here is the relevant introduction to the car body crossing the line when reversing: 1. Steering too early at the starting point: When you first see the corner of the garage in the rearview mirror, it is already very close to the car body, leaving no chance to judge the distance between the car body and the corner of the garage, or even the opportunity to correct the direction. You can only watch helplessly as the car body crosses the line, with no possibility of successfully parking. Steering too early or too late at the starting point will both lead to failure in reversing into the garage. 2. Operational error: Misjudging the distance between the car body and the corner of the garage, missing the best time to correct the direction; when judging the 30 cm distance between the car body and the corner of the garage during reversing, there is a situation that is very close to a one-time successful parking, making it difficult to judge whether it is a one-time successful parking. At this time, the safest approach is to decisively correct the direction, even if it means turning the steering wheel back half a turn and then immediately turning it to the maximum, which will be safer.
