Does leaving a small gap in the car window matter if it rains?

[AnthonyRose]

Leaving a small gap in the car window with a little rain getting in is not a big issue; however, if a significant amount of rainwater enters, it may cause short circuits in some wiring. Safe ways to use car windows are as follows: 1. Opening a single side window: To dissipate gases (like smoke): The main purpose of opening a single side window is to release unpleasant air from inside the car. When smoking, opening the side window quickly expels secondhand smoke, though it may disperse elsewhere, this method is the most effective. Opening the window slightly allows fumes to dissipate faster without blowing directly at passengers in the back. 2. Closing a single front window (for quick odor removal): This means closing the window next to the driver and opening the other three windows. This creates a highly unbalanced air flow with a clear directional movement, allowing odors inside the car to be expelled quickly. 3. Never open windows on the same side at high speeds (dangerous): When driving on the highway, either keep the windows closed or open only one window. Avoid opening two windows on the same side simultaneously, as this causes airflow to rush directly into the car from one side.
