How to Tell if the Car Body is Straight When Reversing into a Parking Space?

[SanMary]

When reversing, if the rear of the car moves to the left, turn the steering wheel to the right to clarify the concept of steering. When the rear of the car deviates to the right, turn the steering wheel in the opposite direction. Check if the parking space lines are parallel by looking at them from both side mirrors while reversing.
