[Pierce]

When the car body touches the line during reverse parking, it means the vehicle has not successfully entered the parking space. Below are the key reference points for reverse parking (using right-side reverse parking as an example):1. First reference point: When the lower edge of the left rearview mirror aligns with the parking line parallel to it, turn the steering wheel fully to the right.2. Second reference point: When the most protruding part of the car body and the right corner of the parking space appear two fingers' width apart in the right rearview mirror, turn the steering wheel one full turn to the left.3. Third reference point: In the right rearview mirror, when the right corner of the parking space points to the middle of the front door handle, turn the steering wheel fully to the right again.4. Fourth reference point: Immediately straighten the steering wheel when you see the left rear corner of the parking space in the left rearview mirror.5. Fifth reference point: The stopping point inside the parking space - stop when the lower edge of the left rearview mirror is about to align with the parking line parallel to it.
