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.

Wasn't it also the door opening mechanism was electronic and it stopped functioning once underwater?

[-] IphtashuFitz@lemmy.world 19 points 8 months ago

Even a purely mechanical door can be extremely difficult to open when partially submerged. The pressure of the water will hold the door shut until the water equalizes on both sides of the door.

But yeah, once totally submerged and flooded an electric door likely won’t open while a mechanical one will.

[-] MataVatnik@lemmy.world 5 points 8 months ago* (last edited 8 months ago)

Yup, that's what I learned about being in a flooding car. Wait until it's filled with water and you'll be able to open the door since the pressure is equalized. But not having the option at all is bonkers, however someone else mentioned that tesla does have a manual lever, in which case it makes this whole debacle even more tragic and stupid.

[-] mosiacmango@lemm.ee 15 points 8 months ago

There is apparently a manual lever hidden underneath the button, but that sure does seem like a bad design idea in an emergency.

[-] iAmNotorious@lemmy.world 17 points 8 months ago

I hate Tesla and traded mine in after only two months of ownership, but in no way is the lever hidden or not extremely obvious. In fact it is more obvious than the button. Several times I had passengers try to use the manual lever, which doesn't lower the window when used. After the second person did it, moving forward I told every person who hadn't been in my car before to use the button before getting out. Was one of the many reasons I traded it in.

[-] rsuri@lemmy.world 8 points 8 months ago

But that's because they were used to other cars. If you're used to pressing the button, that's where you're gonna go in a panic. Fear basically shuts down higher thought processes so you act fast rather than carefully. So the same reflexive action you use to exit in normal circumstances would be the only thing you can conceive of if you're on fire or drowning.

Another detail is that she was on the phone with people as she was sinking

[-] MataVatnik@lemmy.world 3 points 8 months ago

So what happened with this woman dying, could she not pull the lever?

[-] iAmNotorious@lemmy.world 3 points 8 months ago

I have no idea. I wasn’t there and didn’t even know about it until right now. Door could have been jammed shut after the accident like any other door that firefighters keep their jaws of life for.

[-] VirtualOdour@sh.itjust.works 0 points 8 months ago

Yeah it likely sunk into mud thus rendering all the debate over water pressure and lever location mute.

[-] partial_accumen@lemmy.world 16 points 8 months ago

There is apparently a manual lever hidden underneath the button,

"hidden"

[-] RightHandOfIkaros@lemmy.world 7 points 8 months ago

It doesnt look marked to me. If someone saw a door like that they would have absolutely no idea that was a lever/button unless they read through the entire owner's manual. Which let's be honest, nobody does that these days.

[-] partial_accumen@lemmy.world 3 points 8 months ago

Its not the best picture, but it also has finger holds underneath. For someone looking to pull something, this gets pulled.

[-] dotMonkey@lemmy.world 3 points 8 months ago

Is a door handle ever marked?

[-] RightHandOfIkaros@lemmy.world 6 points 8 months ago

Usually manual release safety levers or buttons have red or yellow markings on them, yes. Sometimes they have a logo or icon to denote what they open, and sometimes they are marked with "PULL TO OPEN" or some other similar phrase.

[-] dotMonkey@lemmy.world 1 points 8 months ago

Interesting, I didn't know that, I'll have a look in my car next time I get in it.

Does that only apply to doors than normally have an electronic way of opening them?

[-] Malfeasant@lemmy.world 0 points 8 months ago

Eh, I've seen plenty of internal trunk releases that are just an unmarked handle that pulls a cable...

[-] RightHandOfIkaros@lemmy.world 2 points 8 months ago* (last edited 8 months ago)

I am a professional mechanic, worked at several dealers. Nearly every car had a safety mechanism that was at least one or several of those. The only ones I didnt mention are ones that glow in the dark for trunk releases. But outside of cars that were built before mechanical safety releases were commonly incorporated in design, its not common to see mechanical safety releases that are completely unmarked. Some have a plastic cover, like the transmission neutral release, but they still generally have red/yellow/orange markings, text on them, or they glow in the dark.

[-] Thorny_Insight@lemm.ee -2 points 8 months ago

It could be a massive red lever with "EMERGENCY OPEN" text on it and the Tesla haters would still find something to complain about.

[-] Blue_Morpho@lemmy.world 1 points 8 months ago

This is about the rear door. The rear door manual override is under the carpet here:

The most recent update added a red latch. It's still in the bottom of the door pocket.

[-] Blue_Morpho@lemmy.world 3 points 8 months ago* (last edited 8 months ago)

That's the front. This is about the rear window. Show the rear door manual override.

[-] partial_accumen@lemmy.world 2 points 8 months ago

Why would the driver of this car, which drowned, be sitting in the rear?

[-] Blue_Morpho@lemmy.world 3 points 8 months ago

The title of the article is about passenger/rear seats being hard to break.

[-] partial_accumen@lemmy.world 1 points 8 months ago

Fair point, and no the rear does not have manual release. I wish it it.

[-] HewlettHackard@lemmy.ca 3 points 8 months ago

Now imagine you’ve been driving the Tesla for a long time and don’t ever use the manual release because you’re not supposed to so you don’t mess up the window. And then imagine you’re in a high-stress situation. That’s how having an unmarked backup can fail.

Plus, that handle doesn’t even look like a normal handle - I have never see a car where you pull up to exit instead of sideways away from the door.

shouldn't emergency switch and latched be colored different.
