Should the car window be left slightly open in summer?

[DelLiam]

In summer, it is not necessary to leave the car window slightly open because it is unsafe to leave a gap. Relevant information is as follows: 1. Classification: Car windows are usually divided into four types: front and rear windshields, ventilation windows, heat-insulating side windows, and sunroofs. 2. Function: The front and rear windshields of a car are usually made of curved glass that is both aesthetically pleasing and provides good visibility. In sedans, the front and rear windshields are also known as front and rear windshields. To facilitate natural ventilation, some cars have triangular ventilation windows on the doors, which can rotate around a vertical axis. The front part of the window turns inward while the rear part turns outward, creating a vortex of air that circulates around the window.
