Should the car window be left slightly open in summer?

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.
In summer, I often crack the window slightly while driving, a habit I've developed over more than a decade of driving. Mainly, opening the window a bit helps dissipate the hot air inside the car faster, preventing a rapid rise in cabin temperature. When the car is parked in the sun, it also helps lower the temperature of the dashboard and seats. This reduces the need for air conditioning, which is quite fuel-consuming. Cracking the window with a light breeze makes the car much more comfortable. However, it's important to be mindful of security—I only crack the window when parked in a residential area or under surveillance, otherwise, it might attract thieves. There's also the issue of insects; I've installed mesh screens to keep mosquitoes out, as having a swarm of bugs inside the car is even more annoying. Overall, cracking the window slightly is both energy-efficient and healthy. The ventilation keeps the air inside fresh and prevents odors from building up, which is especially useful during short drives.
I'm a young car owner who loves saving fuel in the summer, and I find cracking the windows slightly quite practical. This allows air to circulate, reducing stuffiness inside the car, so I can set the AC to a slightly higher temperature and save some gas—fuel prices aren’t cheap these days. Just don’t open them too wide; a gap of about 1-2 cm is enough, otherwise the wind noise gets too loud and affects the driving mood. My habit is to open the windows for a few minutes when parked to let the hot air escape, then close them before turning on the AC for better efficiency. Also, a quick reminder about security—it’s best to do this in safe spots like supermarket parking lots, and don’t leave valuables in the car just in case. Combining this with ventilation mode and other tricks, like using a sunshade on the windshield, works even better.
