How to Determine if the Car is in the Middle of the Road?

Here are the methods to determine if the car is driving in the middle of the road: 1. From the driver's seat, observe that the right front outer edge of the road curb or obstacle falls 10 to 15 centimeters inward from the lower edge of the front window, indicating the car's right side is approximately 0.5 meters away from the curb or obstacle. 2. Use the driver's own position as a reference. The position of the left leg corresponds to the trajectory of the left front wheel, while the position aligned with the right leg marks the centerline of the car body. 3. Use the lower edge of the front window as a reference. The trajectory of the left wheel aligns with a point 10 to 15 centimeters inward from the left lower edge of the front window, and the trajectory of the right wheel aligns with the center position of the front window. Below are additional reference materials for determining the car's position: 1. When the line of sight aligns the protruding node of the left wiper with an object on the ground, the left wheel will run over that object while moving. 2. When the line of sight aligns the right wiper with a target, the tire will run over that target. 3. When the line of sight aligns the intersection of the dashboard and the A-pillar with the centerline, the car body is exactly 60 centimeters away from the centerline. 4. When the right washer nozzle overlaps with the edge of the road, the car body is still 60 centimeters away from the roadside.
When driving, I mainly determine if the car is in the middle of the lane by observing the road markings ahead. Generally, there are clear lane dividers in the middle of the road. As long as my wheels are just on the line or the car's position keeps both sides of the body at roughly equal distances, it means I'm well-centered. Another trick is to check the rearview mirror to see if the markings behind the car are parallel—if they are, it's safe. Honestly, this skill takes practice, especially on curves where it's easy to drift. I have to glance at the markings from time to time. Remember, safety comes first, especially on highways where staying centered helps avoid rear-end collisions or being cut off. Occasionally, I exchange driving tips with friends, and they say this method works well—even beginners can pick it up quickly.
