Where is the best position for car mirrors?

[SanWillow]

The optimal position for car mirrors is as follows: for the left side mirror, use the horizon as a reference, ensuring that the sky and ground each occupy half of the mirror, with the car body occupying about 1/4 of the mirror surface. Below are some important considerations for highway driving: 1. Following too closely: Maintaining too short a distance can be dangerous. In emergency situations, trucks, due to their heavy loads, can only slow down but not stop immediately, making rear-end collisions more likely. 2. Forced lane changes: When changing lanes at high speeds, it's essential to maintain a safe distance from the vehicle behind before switching lanes. However, in reality, many small cars often force lane changes without signaling. 3. Overtaking on the right: In China, vehicles are left-hand drive and drive on the right side of the road. This results in poorer visibility on the right side compared to the left. Drivers tend to focus more on the left-side mirror, and the blind spot on the right-side mirror is larger than the left. If a vehicle overtakes from the right, it may go unnoticed by the driver. Given the high speeds, any emergency situation can easily lead to an accident.
