In the past, laminated glass was usually installed in the windshield, with side and rear windows being tempered only.

The difference is that tempered glass is per-stressed so that when it cracks, it shatters into many tiny and dull pieces. Laminated is the same thing, but with layers of plastic sandwiched with layers of tempered glass. Laminated glass will still shatter, but will be held together by the plastic layers.

In an emergency, small improvised, or purpose built tools meant to shatter tempered glass will be useless if the glass is laminated.

    You’re not breaking a tempered glass without the designated tool either and almost nobody has that. There’s this famous clip of a news anchor demonstrating how “easy” it is to break a car window with a hammer and he needed like 8 attempts.

      My algo shows me nonstop car break ins in the Bay area ( for some reason or another) and they have gloves and it’s amazing how quick they shatter.

        Because they have special ceramic tools. Windows will always be incredibly easy for thieves to break with no effort, but they’re incredibly hard for people without specialized burglary tools to break.

            Yeah, they’re nothing fancy, but that’s their sole purpose. People aren’t carrying around spark plugs unless they’re car thieves.

          I’ve seen videos of them shattering when a coffee mug or spark plug hits them. Sometimes it takes a couple tries.

          I’d just like to point out that the same is true of your house. Your average deadbolt and doorknob can be defeated by a cordless drill in less than 30 seconds and with very little noise. Don’t ask me how I know :D

      I don’t know how common they actually are, but I see car window breaker & seatbelt cutter gizmos being sold all over the place. I know I keep one in my car where I can easily get to it, though my car emergency kit is probably better stocked than most people’s, and most first responders also have them in their kit.

      Also an automatic center punch will usually do the trick as well, it’s a fairly common tool, though in an emergency it may not be practical to go rooting through your toolbox to find one.
