What does 'fixed point less than 50 cm' mean?

[McLucille]

In the Subject 2 fixed-point parking test, the announcement 'less than 50 cm' refers to the distance between the vehicle and the sideline being less than fifty centimeters but more than thirty centimeters during slope fixed-point parking. In this case, 10 points are deducted. For slope fixed-point parking, the distance to the sideline should be less than or equal to thirty centimeters without crossing the line. Below are relevant details about Subject 2 slope fixed-point parking: 1. First method: If the car is a new Santana, new Jetta, or new Skoda, there is a 'w' mark at the lower right corner of the front windshield. When sitting in the driver's seat, stop the car when the 'w' mark aligns with the slope starting pole. This is the 100-point position for slope fixed-point parking. 2. Second method: If the car model is not one of the new Santana, new Jetta, or new Skoda, use the lower edge of the left rearview mirror as a reference. When the lower edge of the left rearview mirror is parallel to the upper edge of the second yellow line on the ground, stop the car. This is also the 100-point position for slope fixed-point parking.
