How to Judge a 1.5-Meter Distance Between the Right Side of the Car Body and the Sideline?

Methods to judge a 1.5-meter distance between the right side of the car body and the sideline are as follows: 1. The right one-third of the car's front is the easiest to judge: You can drive slowly with the one-third point of the car's front aligned with the ground sideline and use the rearview mirror to judge. If there is a small rearview mirror on the engine cover, observe the sideline and the car body through the right small rearview mirror—they should either fit together or overlap by half. 2. When going uphill, look at the right one-third position of the car's front engine cover: For the tire position, just focus on the distance on the left side. Parking precautions are as follows: 1. Park in a shaded area; Generally, try to choose a shaded spot in an open-air parking lot, but it's important to note that shaded parking does not mean under a tree. If there are no other shaded areas available, tree shade can be a temporary alternative. 2. Face the rear of the car toward the sunlight; Theoretically, when the front of the car faces the sun, the temperature inside tends to rise faster than when the rear faces the sun. The front interior contains many plastic components, and prolonged sun exposure can cause these parts to age.
After driving for twenty years, I've found that judging when the right side of the car is 1.5 meters from the roadside mainly relies on finding reference points inside the car and accumulated experience. For many cars, when the turning point of the right wiper aligns with the roadside line, the distance is roughly 1.5 meters, but this varies from person to person due to different seat heights. I practiced repeatedly in an empty parking lot: I had a friend help measure the ground with a ruler while I slowly drove closer to the line, aligning the line precisely with the wiper point, then got out to check the actual distance and adjusted my perception. Over time, I could gauge the position without thinking, which makes parking by the roadside much easier. I recommend that beginners practice more on quiet roads when they have time, prioritizing safety over speed. While driving, avoid distractions—focusing solely on reference points can lead to accidents; it's better to develop the habit of observing the overall situation.
When teaching someone to drive, I always emphasize that judging distance using the right rearview mirror is quite reliable. Sit properly in the driver's seat and observe the roadside line in the mirror. If the line appears slightly below the center of the mirror, the gap between the car body and the line is approximately 1.5 meters. Since different cars have varying heights, it's essential to test it yourself: find a safe spot, mark a chalk line, drive over and stop, then take a photo with your phone to analyze the gap. The key is not to memorize it rigidly but to sense the changes in width—when you feel it's wider or narrower, you can make slight adjustments accordingly. During daily practice, avoid staring at the mirror for too long; a quick glance is sufficient, as prolonged focus can be distracting and dangerous. Another tip is that the judgment is more accurate when the car's posture is straight, while errors increase when the car is tilted.
