What is the global impact on society of the invention and subsequent innovations of bulletproof glass?

The worldwide effect that the impenetrable glass has is breathtaking. Covered shatterproof glass has been utilized for windshields since 1927, which has decreased the danger of individuals flying through the windshield of an auto. Treated glass is utilized on the windows of cars so if an auto is struck, and the traveler can't escape through the side entryways, the traveler can kick through the windshield, and it won't influence him.
