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.
It’s one of the various factors.
The whole issue is that those window hammers went work as well with laminated windows, and now laminated windows are mandated. Maybe someone can point to data suggesting that the laminated windows are safer on average for some reason though.
Another is unintuitive door open versus emergency door open. First car I ever saw do that was a Corvette, and yes people have gotten trapped in those without knowing what to do either. At least older Tesla model got it right, the emergency open is opening it harder. Well except exterior handles not working on an emergency, which Cadillac lyric and mustang Mach e also get wrong.
Broadly speaking, also sticking all the features into touchscreen or capacitive touch is also a bad and industry wide trend, which Tesla is the poster child of taking it too far.
Also, early on cars were trying to figure out human factors of transmission, and safety problems caused “PRND” to be mandated. Now we had that actor killed by Chrysler’s fancy shifter, and Tesla also having a weird suffer that might have contributed to this accident.
Also you have the fact you had a pond near a car travel area with no fencing or guardrail. Another is the consequence of choosing to have a private 900 acre residence in a remote area and what that means for speed and quality of rescue attempts. So it’s not all about car design, but there are multi important factors to consider.
Also the thousands of non billionaire deaths we don’t specifically talk about have a lot to say about what we may do better
