How to Judge the Left and Right Distance of the Car Front While Driving?
2 Answers
Here are specific methods to judge the distance while driving: 1. Use fixed reference points on the car to determine the left-side distance. When the midpoint of the vehicle's left rearview mirror aligns with the left sideline, the distance between the vehicle and the sideline is 1.5 meters. When the first wiper node is on the left sideline, the left wheel of the vehicle is pressing on the sideline. 2. When the white line is at the midpoint of the engine hood, the right wheel of the vehicle is already pressing the line. When the white line is at the halfway point on the right side of the engine hood, the vehicle is 30 centimeters away from the right sideline. When the line is at the one-third point on the right side of the engine hood, the vehicle is 60 centimeters away from the right sideline. 3. When the distance between the vehicle and an obstacle vehicle is 20 centimeters, the lowest visible point of the obstacle vehicle is at 80 centimeters. For sedans, 80 centimeters is roughly below the door handle, while for SUVs, it is around the lower edge of the headlights. Therefore, when approaching an obstacle vehicle, ensure you can see below the door handle or the lower edge of the headlights.
Having driven for over a decade, I rely on accumulated experience and practical exploration to judge the distance between the front of the car and obstacles on either side. While driving, I keep a close eye on road conditions. For example, when parking in a lot, I observe the relationship between the front edge of the car and roadside obstacles. When turning left, I focus on the shadow of the left tire or the height of the curb; when turning right, I glance at the alignment between the right corner of the car and the pedestrian line. I slow down and release the accelerator to gauge the distance. When I have time, I practice in a safe open area with cones, repeatedly moving in and out to develop intuition. Additionally, checking the side mirrors to see the gaps between the car body and obstacles helps build spatial awareness, especially on narrow roads. Over time, even driving through busy alleys doesn’t worry me about scraping anything.
