What are the techniques for accurately judging the 30cm distance when reversing into a parking space?

Here are the techniques for accurately judging the 30cm distance when reversing into a parking space: 1. For the standard 30cm reference point when reversing into the parking space, turn the steering wheel fully to the right at the reference point during right-side reversing. Observe the right rearview mirror and notice that the car body gradually approaches the right corner of the parking space under these standard conditions. 2. At a certain moment, the right side of the car body will start to cover the reference point, but it should never completely cover it—at least a small part of the reference point should still be visible. This means the car is approximately 30cm away from the parking space. At this point, the 30cm distance is the standard reference point for reversing into the parking space. Finally, when entering the parking space, the outer edge of the rear wheel should just pass over this reference point for a perfect entry. Additional information: Here are some precautions for reversing into a parking space: 1. Do not go too fast: The most important aspect of reversing into a parking space is to go slowly, so that in case of a mistake, the brain has enough time to think and react accordingly. 2. Avoid repeatedly adjusting the steering wheel after entering the parking space: If the distance on either side of the car is uneven after reversing into the parking space, try to avoid repeatedly adjusting the steering wheel to prevent the situation from getting worse. Generally, steer towards the side that has more space.
When I reverse into a parking space, accurately judging the 30cm distance can be maddening, especially with obstacles that increase the risk of scrapes. My trick is to fully utilize the vehicle's technology, such as the rearview camera and parking sensors. First, check if the rear camera is properly calibrated—image clarity directly impacts distance estimation; the digital display or on-screen guidelines often mark the 30cm point clearly. If your car lacks these features, installing an aftermarket rear parking sensor is highly practical—the beeping frequency intensifies as you near obstacles. Additionally, I’ve learned that regular maintenance of these systems is crucial: dust-covered lenses or faulty sensors can mislead your judgment, so weekly cleaning ensures reliability. Another handy tip is using physical markers, like bright stickers on the garage wall as a visual guide, but technology remains the most dependable aid—especially for novice drivers—saving time by eliminating constant stops to check. In short, leaning on modern tools significantly boosts reversing safety and efficiency.
