What Are the Advantages and Disadvantages of Rain Guards?

Rain guards have the benefit of being unaffected by external environmental conditions, but the drawback is increased wind noise. Below is a detailed introduction to the pros and cons of rain guards: Advantages of rain guards: They allow you to handle various harsh weather conditions by enabling the window to be opened slightly above the rain guard, providing ventilation inside the car without being affected by external weather and reducing fogging inside the vehicle. When you need fresh air, rolling down the window allows airflow to enter without directly blowing onto your face, ensuring comfort for both the driver and passengers. They block glaring side light and UV rays, lowering the interior temperature, and prevent rain, snow, and dust from entering the car while still allowing air exchange. They also reduce the impact of strong side light on driving visibility. By avoiding direct sunlight exposure, they help regulate the interior temperature. Disadvantages of rain guards: When driving at high speeds, rain guards significantly increase wind noise, which can affect auditory perception while driving. They also lead to higher fuel consumption due to the increased aerodynamic drag caused by the rain guards. Additionally, they can obstruct visibility, especially darker-colored rain guards, which may create visual barriers.
As a veteran taxi driver with ten years of experience, I find rain guards quite practical. The advantages are: they make it very convenient to open the window for ventilation during rainy days without letting rain directly splash in; they allow leaving a small window gap for heat dissipation when parked in summer without worrying about sudden rain; and they help reduce window fogging on foggy days. However, there are obvious drawbacks: wind noise becomes very loud at speeds above 80 km/h, like a whistling sound; they make the side profile of the car less sleek; and if not firmly attached, they might come off when hit by high-pressure water jets during car washing. After more than three years of use on my car, the edges of the adhesive strips have started to lift slightly. I recommend choosing transparent acrylic material to avoid obstructing visibility when driving at night.
