[LaCamila]

4S store replaced glass is original. Relevant information about automotive glass is as follows: Development history: When motor vehicles became more common and their speed increased, wind and small debris hitting the driver's face became an increasingly serious problem. To reduce this trouble, manufacturers added a piece of glass to the vehicle, literally called a windshield. The new windshield made drivers more comfortable, but it was still not enough to resist flying small debris. These initial windshields were manually cut from flat glass. Unfortunately, when the glass broke, the flat glass would shatter into large, dangerous, sharp fragments, which did not seem to possess the satisfactory qualities of a windshield. Tempered glass: Another type of safety glass, widely used in modern cars for side and rear windows. Compared to laminated glass, tempered glass increases strength through heating and pressurization. When damaged, it shatters into smooth, small particles resembling breadcrumbs, thereby reducing the possibility of injury from glass fragments.
