What is the reason for the fog on the window of popular cars?

In winter, due to the large temperature difference between the inside and outside of the car, many friends will encounter fog on the window, especially in rainy and snowy days. Don't underestimate the fog on the window, which will affect the driver's sight and bring safety hazards to the driver. So, how to deal with the fog on the window? Here are a few tips for defogging.

If you find the window foggy, don't panic. You can open the windows on both sides of the car with the width of your fist. This makes the air inside the car convection, blowing away moisture, and the fog will soon disperse.
