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 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.

      pretty insane that cars don’t just come with the tool already in a special holder at the bottom of the door “pockets”

      like it would cost them dollars to do so, no one will notice if you just bake that into the price of the car and i do believe it’s generally considered a good idea to keep your customers alive so they can buy another car.

        They’d go the way of the cheap little tire change kit, if the car even has a spare. Nobody would remember where it is, and it’s probably buried under whatever junk is stuffed in the pocket.

          It pisses me off to no end that 2 of the 3 cars I’ve owned have not had a spare, but that shitty flat repair kit. Thankfully, the one time I needed a spare I had one, as the flat repair kit would have been worthless the day I clipped a curb on a turn and completely blew out my tire.

          Fucking cheap asses making life harder for people…

            Yep. The shrinkflation of cars. Cutting out extras like spares to save a buck. Yeah it’s weight that affects economy, but I don’t want to calculate the weight of a 40lb spare on gas consumption vs the cost of the tire or a tow service. FWIW the do make these little collapsible/inflatable spares that can fit in small spaces, but I’d be wary of them with some AWD cars. Can really F up the limited slip allowed in some of the systems.

              That honestly sounds worse than using a donut, and the one car that came with a donut got it replaced with a full-sized spare because fuck donuts.

        It seems that you don’t know the lengths auto makers will go to save litteral cents on a model line. Adding dollars is absolutely not something done lightly.

          Doesn’t cost dollars, literally cents. A tiny hard rock super glued to the key fob should be enough to shatter the tempered glass

            Yes, but remember that you’re dealing with MBAs who make it their sole purpose to save pennies. Pennies saved on a few million cars equals more than their salary, which means they keep their job. So fuck a few people dying.
