What is the purpose of a car sunroof and why is it only a panoramic sunroof?

Firstly, sunroofs are designed and function for lighting. In order for a car to have better light, a sunroof can be used to supplement the light inside the car. Drivers who like the sun will love sunroofs, but many drivers don't like a bright driving view, so sunroofs are being driven. It will be more of a chicken feed.

　　In addition, the sunroof is superior to four windows for ventilation and airflow. When the sunroof is open, it satisfies the need for ventilation and airflow. However, it can also be too fast if the weather is cold or windy. It feels like the wind outside the window is in your face, very cold, even chilly. Only when the temperature is higher, the whole ventilation process of the sunroof is more comfortable for the passengers in the car. Now, summer is coming. Open the sunroof and change the air temperature. When air conditioning is not needed, it can lower the temperature inside the car. When the car is moving, the car is stuffy. It is uncomfortable to drive.

　　In winter, the temperature difference between the inside and outside of the car is very large, and the windows are easy to fog up, which affects the view inside the car. At this time, if the sunroof is open, it will not be very cold and it can quickly eliminate fog.

　　Driving on a noisy road, opening the sunroof helps to reduce the noise inside the car and prevent exhaust fumes from entering the car. At this point, the air quality inside the car is obviously due to the closed car.
