It depends on the driver's personal habits. Installing small round mirrors on rearview mirrors has both advantages and disadvantages. Here are the details: Advantages: Makes reversing more convenient. Through the small round mirror, you can clearly see the rear wheels and parking lines; Provides a wider field of view to avoid accidents. Before changing lanes, cars equipped with small round mirrors can promptly see vehicles behind, making lane changes safer; Protects the car body. With an increased field of view, you can see more objects, avoiding incidents of the car body being scratched. Disadvantages: Distortion and distance can be easily misjudged. A car that is actually only about two meters away may appear much farther in the small round mirror; Additionally, when using the rearview mirror while driving, constantly focusing on the small round mirror can easily distract attention.

Having driven for over a decade, I deeply understand: car blind spot mirrors are absolutely necessary to install. They fill the blind spots of rearview mirrors, especially allowing clear visibility of rear tire positions when reversing, avoiding scraping against roadside obstacles. In my actual driving experience, before installation, I always felt uncertain when changing lanes; after installation, the wider field of vision significantly improved safety. Just pick a simple adhesive type and stick it on the outer corner of the mirror—it costs only a few dozen yuan but contributes immensely to driving safety. Especially for beginners or drivers frequently navigating narrow urban roads, this small device can make the entire driving process more confident and smooth.

Will the Car Lock Itself If the Key Is Left Inside?

If the car key is left inside the vehicle, the doors will automatically lock. After the engine is turned off, if the doors are closed without taking the key, both the doors and the rear hatch will automatically lock after a few minutes. This feature is designed to prevent the owner from forgetting to lock the car. When exiting the vehicle, the owner should turn off the engine, remove the key, and keep it with them. If exiting the vehicle while the engine is still running, it is essential to ensure the handbrake is engaged, the doors are not fully closed, or the windows are rolled down. Precautions for using car keys: 1. Do not leave the spare key inside the car or together with the smart key; 2. Avoid contact with metal objects. If the smart key comes into contact with or is covered by metal objects, it may malfunction. Additionally, other items in a bumpy environment could potentially damage the smart key.
