It is necessary to install a reversing radar. Here are some relevant introductions about reversing radars: 1. Working principle: The PDC system works by usually installing radar detectors on the rear bumper or both front and rear bumpers of the car to detect obstacles in front and behind, helping the driver "see" obstacles in front and behind, or the distance from other cars when parking. In addition to facilitating parking, this device can also protect the car body from scratches. 2. Function: When reversing, it helps the driver "see" things that are not visible in the rearview mirror, informing the driver of the surrounding obstacles through sound or more intuitive display, relieving the troubles caused by the driver looking around when parking, reversing, and starting the vehicle, and helping the driver eliminate blind spots and blurred vision, improving driving safety.
A rear parking radar is absolutely necessary to install! As a veteran driver with ten years of experience, I initially thought I could rely on my skills to reverse without any issues. However, one rainy night, I almost hit a fire hydrant while backing up. The radar can detect blind spots that rearview mirrors can't cover, making it especially helpful for beginners. Nowadays, parking spaces in cities are narrow, with electric bikes and bicycles darting around unpredictably. The radar beeps when approaching obstacles, which is much more reliable than turning your head to look through the rear window. It's also affordable—just 300 to 500 yuan—and the money saved on repairs could cover the cost of installing ten sets. I recommend getting a model with audible beeps; the closer you get to an obstacle, the faster the beeps become, making it more intuitive and safer than relying solely on visual feedback.
As a parent who drives kids to school every day, I highly recommend installing a reverse parking sensor. Kids often suddenly run behind cars in our neighborhood, and rearview mirrors simply can't react fast enough. My car has an 8-probe radar system (front and rear) that starts beeping when obstacles are within 1.5 meters. What's particularly useful is its ability to detect low-lying objects like pets or stone piers that rearview cameras often miss. Last time when I was reversing, the sensor suddenly went crazy - turns out there was a scooter behind me. Without the sensor, I would've definitely had to pay for damages. Installation is quite simple, any auto repair shop can do it in about two hours. Just remember to have the probes cleaned during monthly car washes.
