Why is the reference point different every time when reversing into the garage?

[SanChristopher]

Reversing into the garage with different reference points each time is because the viewing position is affected by the seat position and the angle of sight. Related introduction: 1. Brief introduction: Reversing into the garage is a mandatory test item for obtaining a small car driver's license after 2013. It assesses the driver's ability to operate the vehicle in a confined space. Reversing into the garage is one of the assessment points in the driver's test, which involves correctly maneuvering the vehicle into the garage from both sides while in motion. 2. Expansion: There is a time limit for reversing into the garage during the test. The three most common types of reversing are: the first is the "non"-shaped reversing into the garage, commonly seen in large shopping malls; the second is the roadside "one"-shaped reversing into the garage, also known as parallel parking; the third is the less common diagonal reversing into the garage.
