Vehicles for the sunroof glass strength and broken requirements are actually very high. Many businesses choose metal glass, its hardness is close to the metal, strength is even ten times higher than tempered glass. And the glass will become obtuse angle after broken fine particles, not easy to cause harm to the human body.
