Victims, bystanders, etc always want to marvel about how "it's a miracle that they walked away completely uninjured". But it's not a miracle. *It's meticulous engineering designed to substantially protect the passenger compartment.* A lot of people worked really hard to make those "miracles" happen.

I've been a paramedic for almost 15 years, and it's actually awe inducing how incredibly *SAFE* cars have steadily become, starting in the mid 90s or so. If the vehicle is like 2005 or newer and the occupant has sustained serious injuries, I can almost guarantee that it's because they either weren't wearing their seatbelt (properly) or they were riding with their feet up on the dash. In those cases, it's like the occupant has slammed into a solid stationary object (often head first) while flying along at high speed. And engineering has even worked hard to address the issue of seatbelt haters lol newer vehicles have a setting where the vehicle cannot be shifted out of park if the drivers seatbelt is not latched. Depending on the vehicle, this also applies to the front passenger seat if sufficient weight is detected in the seat. Of course, freak accidents do still happen and it _is_ possible to slip out of a properly worn seatbelt (and possibly be ejected from the vehicle) in a rollover. But overall, the safety improvements are just incredible!

Annoying afffff when boomers and gen x look at modern cars and start whining about how they "sure don't make em like they used to"... Yeah, they're like 9 million times safer now _because_ of stuff like all that crumpled aluminum. And it's not _just_ that they're 900 99 million times safer, they're also way more fuel efficient thanks in part to all those cheap impact absorbing materials.

I have both types. Specifically because I spent like 30 minutes at Home Depot reading all of the information on every single smoke alarm lol

There was zero reason to keep playing the alarm over and over. At best, it's obnoxious and pointless to show it going off so many times. At worst, it's super triggering and upsetting. In addition to the intentionally distressing sensory aspect, it's also a sound that's tied to an intensely traumatic event for for more than a few people out there. It's a sound that can be tied to losing everything especially irreplaceable sentimental items. To being trapped in a life or death situation. To getting horribly burned. To losing someone you loved. Not to mention all the guilt a lot of people feel over failing to prevent the fire or rescue someone/something. Even if you have zero experience with these alarms, you really only need to see it going off for no reason in the kitchen to get the feel. And for anyone who might want to comment saying "I loved hearing the alarm go off so many times! It added so much to the video!", *no you didn't*. You just love Andrew. And me saying something critical about the video is making you feel protective and defensive on his behalf. _I love him too, so I fully understand. But this particular criticism is actually really important, I promise._

3:39 glad my home city's public transportation got the spotlight. I feel honored

it s over for airbagless project car owners fr

Ionisation smoke detectors are forbidden in Germany since a few years due to the radioactive source.

Fun fact, we go faster that 30mph fairly often

“I discovered” 😂

Interestingly, can't find any detectors meeting the new requirements for sale in Canada.

As someone who rides a motorcycle, this is highly useful information

I'm NOT a fan of First Alert's battery-operated alarms. Twice now, I've had their products suddenly go into full alarm in the middle of the night with no way to shut them up (other than a hammer). Just happened to me this past week, AGAIN...and this smoke detector was a replacement for one which did the same thing just 3 years prior. Both supposedly had "10 year batteries", permanently sealed. It's bad enough to have one start chirping in the middle of the night. Going into full alarm and the silence button not working at 3am is completely unacceptable. So here I am at 3:30am, half-asleep, having to drag the ladder up from downstairs, climbing on top of it (half asleep) trying to get this POS off the ceiling. Then there wasn't any way to shut it up! Sure, there's a switch on the back, but that requires breaking some plastic tab off...which requires tools. again, it's 3:30 AM in my bedroom... A hammer in the hallway closet was the nearest tool, so that's what I used on it until it finally shut up.

I think the real question is; When does a car start being safe?

My fire alarms are over 30 years old. Lol

This is just why I installed a commercial fire alarm system in the house, I use a Hertek Penta 5000 Addressable FACP with Apollo XP95 smoke and heat Detectors with sounderbase, and I also use Apollo MCP’s. Those XP95 detectors sense small smoldering fires. I also got magnetic firedoors that releases when the alarm goes off and the system sends me a sms and email notification when a system trouble or alarm occurs. I all monitor this system myself.

These Japanese engineers stole my college project 🤬🤬

This is my new favorite channel.

6:10 That's nonsense, "synthetic materials" can have basically any property you want. The problem is that most of the time the only property manufacturers care about is cost.

My alarm goes off for steam, smoke, even just DUST when I’m cleaning It makes me so annoyed! Thankfully I just need to take it down, hold the button and cover it in a towel. To be fair- it does trigger with almost no smoke but it’s getting too much

The whole city can flood but please leave the football field alone😭

Oh wow, that 70s era smoke alarm was the exact model of alarm in the house I moved into in 2019. And the ONLY one 😱

I have heard some people are against what I am going to call "Smart Sensors" in the 8th generation Ionization Sensors. The reason being that computer algorithms are not perfect, and if it is able to figure out if it is cooking smoke, on not trigger the alarm, then it could think it is cooking smoke, and not trigger the alarm, even if it is a real fire. This also makes no difference that ionization sensors still don't work at all with very thick smoke.

See smoke not smell it..... photo electric

Outstanding video. Thank you.

There is a mistake in the chart at 11:41 where the chart shows that PhotoElectric took 35 minutes, but you mention that it was faster to detect the fire. Edit: it seems that the "warning time" is not a good title for the chart, safe egress time and evacuation time make a lot more sense.

Recap: Ionization: better at detecting fire. Photoelectric: better at detecting smoke. NEW ionization (gen.8): better at everything. Also, make sure to check your alarm from time to time. There's a test button on it. Use it.

So humans can still collaborate to just make things work better lol. Sometimes I feel like capitalism causes people to horde knowledge instead of share it. So we are stuck with crappy products forever, designed to fail, instead of just making stuff effeciently.

What about INDUS VALLY?

I thought its because people dont change the battery

You didnt explain what the escape time is

Interconnection might be great if you have a very large house where you can't hear an alarm from the other end of the house. Or if you're the type that's immediately going to flee from every little beep and stand outside on the phone with the fire dept while your house burns down. Same type of idiot who tells the dispatcher his smoke detector is going off and causes a code 3 fire response when it's a CO alarm which he could have handled himself. Me, I want to know immediately WHERE the fire is so I can put it out before major damage is done. Interconnection means I have to walk the whole damn house before learning anything. And I could become trapped in the process. Whereas if it was a single alarm beeping I'd be able to tell by sound whether a given path was safe.

8:00 "since we don't live in a world with unlimited money" should be: since we don't live in a world with unlimited recources. since money is but a means to an end.

Watching this while driving 🔥🔥🔥

Due to strict regulations, ionization detectors in the European Union are now only used in exceptional cases. However, the risk potential of a single detector is low when used and disposed of properly. Normally, ionization detectors are completely harmless due to their low activity. After a fire, the debris must be searched for missing fire detectors. If not all detectors are found, the entire debris must be disposed of as hazardous waste according to radiation protection regulations (at least within the EU), which can cause significant additional costs after a fire department intervention. Searching for the detectors is not always easy. With Geiger counters, there is hardly any chance of finding them under a layer several centimeters thick.

Exactly! Just put 2 alarms, it's that simple.

My dumb ass: maybe it's because it's smoke not fire

I havent got a smoke alarm

North American here. We have photon detectors here because local fire chief for 15 years has been very persistent *DO NOT BUY KIDDE BRAND. THEY FREQUENTLY FAIL AND YOU'LL DIE*

I can tell this is not true for us because a little humidity from outside sets it’s off

Idunno about yall, my houses uses the 1776 fire detection method You just kinda find out when you find out when you do, you know?

Land Rover Range Rover SV Autobiography

in 2024 this is still an amazing budget camera

Cable barriers are good and all but I heard a story of a biker hitting one and was cut in three

This is such a cool video, great work, thanks

That's why I have a fire alarm SYSTEM with several detectors on multiple loops for each zone of my house cause typical home smoke alarms are terrible at protecting people

I wonder what's the performance of those safety features in regard of modern heavy "SUV" and new electric cars

Here in Philippines had 5500 flood control, tapis binangaga ng barko nasira lahat ang 5500 na flood control😅😂🤣

I dont think I have ever seen a ionizing detector here in Norway
