Is it necessary to install rain guards on a car?

[LeKiara]

It is not necessary to install rain guards on a car, but if the owner lives in a city with frequent rainy weather, adding rain guards can make driving more convenient. Rain guards are mainly installed on the left and right rearview mirrors and side windows of the car, serving functions such as maintaining clear visibility in the rearview mirrors, avoiding rain, and blocking sunlight. Generally, rain guards can be divided into acrylic rain guards and polyethylene rain guards based on their materials. Advantages of rain guards: 1. They allow the window to be opened slightly for ventilation during rain, preventing rainwater from entering the car interior; 2. They can block direct sunlight from hitting the driver to a certain extent; 3. Installing rain guards on the left rearview mirror can prevent rainwater from blurring the mirror, enabling the driver to better judge the vehicles behind.
