There are little window breaker tools made by a company called resqme which are worth having in your car.
- Yeul 1y agoWindow breakers come standard with a new car in my country. I have never used one though.
- tzs 1y agoNote that these tools only work on tempered glass. Many newer cars are switching to laminated glass. Some have a mix with say a laminated windshield but tempered door windows.
- Ekaros 1y agoHaven't the windshield been laminated for very long time now? For Britain it seems safety glass was mandated in 1930.
- tzs 1y agoThe term "safety glass" just means glass designed to minimize injury when broken. There is laminated safety glass and temperated safety glass. Laminated glass has at least two layers of glass bonded together with a plastic layer between adjacent glass layers. When broken it just forms webs of cracks but the pieces stay in place. This keeps you from getting ejected or cut by the glass. Tempered glass on the other hand is made by rapidly heating and cooling the glass in such a way that it solidifies with a lot of internal stress. The glass at the surface ends up under compression and the interior glass ends up under tension. If you break the surface it releases all the stress rapidly resulting in the whole sheet quickly shattering into a very large number of small rounded pieces. It won't keep you from getting ejected but the small rounded pieces should only inflict relatively minor injuries. Tempered costs less than laminated. Most countries have long mandated laminated glass for windshields but allow tempered glass for side and rear windows. Some car makers choose to use laminated for side/rear windows to make it harder for thieves to get in, or for people to get ejected out side windows during accidents, better UV blocking, and better soundproofing.
