Are Car Rain Guards Useful?

[VanCarmen]

Car rain guards are useful as they allow for window ventilation and cooling. Below is a detailed introduction to the functions of car rain guards: Rain guards enable window ventilation: The role of rain guards on car windows is significant. During rainy weather, the car interior can feel stuffy, and turning on the air conditioning might make it too cold. Installing rain guards allows you to open the window slightly—though not much, as rain guards are generally not very wide—but enough to let fresh air in and expel stale air from the car. Rain guards help cool the car by opening windows: In the high temperatures of summer, the car interior can reach 40-50 degrees Celsius or more after being parked in the sun. Even if it suddenly rains, the air inside the car cannot circulate. However, with rain guards, you can open the window slightly even during rain, allowing air to flow and significantly reducing the temperature. Drawbacks of rain guards: They can create blind spots by obstructing part of the driver's view, which is worse if the rain guards have poor light transmission. Therefore, it's important to be careful when selecting them. Another issue is noise. Installing rain guards adds an obstruction to the car, increasing wind noise during high-speed driving.
