How to Determine the Distance Between the Left and Right Corners of the Car Front and Obstacles
2 Answers
Methods to determine the distance between the left and right corners of the car front and obstacles mainly include the following scenarios: 1. If the obstacle is a pedestrian: When you can see the pedestrian's heels, the distance between the car and the pedestrian should be about 4 meters. 2. If you can see the pedestrian's knees: The distance between the car and the pedestrian should be about 2.5 meters. 3. If the obstacle is another car: Focus on the front car's bumper. The rear of a sedan is generally about 42 centimeters from the ground. When you can see the lower edge of the front car's tire, the distance between the front car and your car should be about 4.6 meters.
When I first started driving, I was also very afraid of scratches. Later, I figured out some tricks: adjusting the seat to maintain a fixed sitting posture is key. When looking at the left corner of the car, I focus on the leftmost edge of the hood. When it just blocks the bottom of the obstacle ahead, the distance is usually about half a meter. The same principle applies to the right side, where the positioning node of the wiper can be used as a reference. I practiced dozens of times in an empty parking lot using soda cans as reference objects. At one meter away, I could still see the full outline of the can, but at half a meter, only the top remained. Later, I realized that the darkness of the window tint affects judgment, especially in dim evening light. So now, I always turn on the front radar when entering narrow alleys for double assurance. Remember to always confirm the position of the front reference point when adjusting the rearview mirrors.
