Actually, windshield glass is designed to prefer cracking (and holding together) instead of shattering into chunks when it breaks like the side windows.

Relevant video about this design: https://youtu.be/aAsUG-jbLlM?t=131

Computer screen glass is also usually laminated (though here the goal is to fuse the glass very closely to the LCD panel so there's no unsightly "air gap")



There used to be a science show on German television that always demonstrated interesting engineering science bits at prime TV hours (knoffhoff show). They demonstrated windscreen security glass by someone jumping on a large (2mx2m or more) sheet between two wooden blocks. It looked like someone jumping on a springboard. At the end another person tapped the side of the glass using a small hammer and the glass shattered into tiny little pieces. The jumping guy was still on it, but did not get cut because all pieces where dull shards.

It really impressed my young self at the time.


Saying you are about 50 years old without saying you are about 50 years old :-)
