What is the impact of seat height on reference points in Subject 2?

[SavannahFitz]

Subject 2 seat height mainly affects the timing of operations. After adjusting the seat, the reference points will change, which significantly impacts Subject 2 performance. Maneuvers such as hill starts, right-angle turns, S-curve driving, reverse parking, and parallel parking all rely on reference points. Generally, if the seat is raised, the timing of each operation needs to be delayed; if the seat is lowered, the timing can be adjusted earlier. It is recommended to fix a position when learning to drive and adjust it to a familiar and comfortable position during practice. When candidates begin the Subject 2 test, they should first adjust the seat so that there is at least a fist's distance between the head and the roof of the car. It is essential to remember the number of notches moved forward or backward, and the backrest must be at a 90-degree angle to the seat. The distance between the top of the head and the car roof can be measured with fingers or tools. When the foot presses the brake pedal to the deepest point, the leg should still have a slight bend, indicating the seat's optimal position.
