How to Judge the Left and Right Distance of a Car While Driving?

Methods to judge the left and right distance of a car while driving are: 1. To judge the position of the left wheel, when the driver sees the wiper node coincide with the centerline of the ground, the left tire will run over the target. Flexibly judging the running track of the left tire can avoid potholes and stones on the road; 2. To judge the position of the right tire, when the driver's line of sight intersects the node of the right wiper and the target, the tire will run over the target line. Methods to judge the distance from the car in front are: 1. When the upper edge of the front car's bumper is seen from the lower edge of the windshield, the distance from the front car is about one meter, and the distance needs to be controlled; 2. When the lower edge of the front car's bumper is seen from the lower edge of the windshield, the distance from the front car is about two meters; 3. When the rear tire's lower edge of the front car is seen from the lower edge of the windshield, the distance from the front car is about three meters.
In the past, I often worried about the sides of my car being too close and scraping against objects, such as in narrow alleys or when parking. Experience has taught me a simple method: after adjusting and fixing the seat position, observe the relationship between the edge of my car body and the roadside white line in the left rearview mirror. If the white line is still in the middle of the mirror, there is approximately half a meter of space on the left. The right side has a much larger blind spot, so I often turn my head to check the right window to ensure there's nothing there. Another trick is to use the wiper nodes as a reference—when the wiper aligns with the curb, the right side of the car is roughly aligned. On highways, use the width of the lane markings to judge if you're centered; align the front of the car with the inner side of the line and maintain a steady speed. Practicing reversing into parking spaces in open areas or parking lots helps quickly develop a sense of distance, making city driving less daunting.
To accurately judge the left and right distances of a car, a combination of vision and practice is essential. From years of driving experience, I've learned the following methods: adjust the rearview mirrors to cover as wide an angle as possible, with the right mirror slightly tilted outward to see roadside objects. When parking, I observe the relative positions of the car body and obstacles, such as when the wheel hub aligns with the curb, indicating a safe distance. Slowing down makes it easier to control, and checking the A-pillar blind spot before turning prevents sudden lane changes that could cause accidents. Modern vehicles with 360-degree cameras can assist, but the foundation still relies on habits, such as estimating gaps in urban traffic based on the sizes of surrounding vehicles. Consistently checking mirrors while driving and accumulating experience can significantly reduce the risk of scratches.
I started practicing judging left and right distances when I was a beginner driver. Initially, I relied on a few tricks: checking if the outline of my car was clear in the left side mirror—if it appeared blurry, it meant an object was too close; and turning my head to scan the right blind spot for safety. During daily driving, I used the central rearview mirror for assistance—when the car behind appeared to grow larger in the mirror, it indicated a shorter distance. When parking or reversing, I tried using ground markings as reference points, making slight adjustments each time and stepping out to confirm. Repeating this a few times helped me get the hang of it. Remember to maintain a consistent seating position—developing good habits builds confidence in driving.
