and today, we're taking a look

at some of the most dangerous tech out there.

This is a Tesla Model 3,

and it is a very good car.

What it is not,

is a self-driving car.

While the sensors in self-drive have come a long way,

and they continue to get better and better,

it is not yet ready for a full self-driving experience,

something that a lot of people should really take note of.

There are several cases where people

have gotten into major accidents or straight up died

because their cars either ran into someone else,

or someone ran into them,

and they were just weren't paying attention.

Even though it's not full self-driving,

auto-pilot is a legitimately really impressive technology,

and especially when you pair that

with navigate on auto-pilot,

which allows you to put in the GPS coordinates

and the car will essentially drive you there, it's cool,

but you can't fully trust it.

So auto pilot is not ready for full self-driving just yet.

So especially here on like a normal street,

you really don't want to use it, right?

It's really meant for freeways.

Now there are a lot of people who think

that full self-driving is here right now,

and that's just simply not true.

Now there are a lot of cars which are getting

closer and closer,

but the full self-driving experience

is still a little ways away.

That being said though,

what Tesla has here is one of the most advanced systems

that you can buy.

So you look at the screen here,

it can easily the car in front of us,

the cars to the side of us.

It's actually pretty clever with that.

Okay, it's vibrating now,

it's letting me know that turn signal's on.

There is a car coming past me,

and now it should be clear, is it clear?

It is clear and we are changing lanes.

Okay, that's pretty cool.

A little scary, but that worked.

So this is actually a sketchy place.

If I'm driving right now,

I am not going to try to change lanes

while I'm almost stopped and there are cars flying around,

but, okay it's going to try to get over.

Oh man, there's cars coming pretty fast

on this side.

I can see them though.

It's not doing anything too stupid.

K, I see there's one more,

oh God, oh God don't do that!

Nope nope nope!

Okay, (laughs) yeah that was a bad idea.

And that's the thing with these systems.

They are assistant tools.

They're not full self-driving, right?

There's a lot of stuff that it can do,

but if you're not paying attention,

you will straight up be in a world of

insurance claims, and maybe even worse.

When we're talking danger tech,

one of the things that's been doing

the rounds lately is 5G.

Now this one is, shall we say, controversial.

Now there is absolutely no doubt that

we live in a world filled with radio signals,

cell phone towers, cell phones in our pockets,

maybe smart watches on our wrists.

I mean there's absolutely this stuff

all around us every day,

but the thing is, there is really no true evidence to prove

that this is actually harmful.

Today though, we are on the cusp of a brand new 5G network,

which promises hugely improved speeds.

I mean, you look at these Samsung Galaxy Note 10 with 5G

and this thing is rocking speeds that are a lot faster

than most peoples' home internet connection.

And this is certainly not going

to be the first or last phone we see.

There are lots of 5G networks which are

really going to become ubiquitous

over the next couple years.

Now though with the dawn of 5G networks,

people are again asking the question, is 5G safe?

(intense drum beat)

Yeah, it's safe.

It's fine, don't worry about it.

All it takes is a quick Google of 5G

and 5G dangerous quickly shows up.

But the thing is,

there's really no evidence to show that 5G

is any more dangerous than all of the wonderful networks

that have come before it.

(bird screech)

That's a really annoying Seagull.

I think that Seagull likes 5G.

Now there is absolute truth in the fact

that there is some danger when it comes to radiation,

however, radiation is absolutely everywhere around us.

Now if you look at the electro-magnetic spectrum,

I mean, sure,

things like x-rays and sort of iodizing radiation is

certainly not something you like,

but 5G is no where near that.

And in fact, even in visible lights on the spectrum,

and I've gotta say, I'm a huge fan of visible light;

can't see anything without it.

But simply, there is no need to fear 5G.

It uses very similar frequencies to W-Fi

as well as cell towers of today.

Really, the most dangerous part of your smart phone

is like, dying while taking a selfie,

or neck strain,

or a general lack of not having any self respect

after spending all day on Twitter.

But that's probably more of a personal issue I think.

(beep)

Dude, is this a Note 7?

- Yeah - What are you doing?

No, no dude. - No, it's fine

- This is literally going to explode.

- Dude no, dude, it's fine.

It's the fan edition.

It's the fan edition. - Oh.

- [Man] Someone from south Korea.

- Oh.

Now Samsung is in the news right now

for the slight issues that the Galaxy Fold has had.

But beyond something like a foldable phone,

the real PR disaster was the Galaxy Note 7.

This still makes me uncomfortable to hold.

But real talk though,

this was a major PR disaster, right?

I mean, you're talking about a huge flagship phone

that the battery was literally catching on fire.

And as you'll see in see in a lot of these other

sort of danger tech things that we're talking about,

batteries, they're dangerous.

They straight up catch on fire sometimes, right?

I mean even plain batteries.

Like, I don't know if you remember the Boeing 787.

When it first came out with the Dreamliner,

there were issues where the Lithium-ion batteries

on board would just catch on fire randomly.

You know, no big deal when you're 40,000 feet

and super low oxygen and planes, air disasters.

Even Apple was out here with issues.

With older MacBook Pros being recalled

due to battery issues,

some airlines are straight banning MacBook Pros right now.

In September of 2016,

Samsung officially started recalling their Note 7.

Now they were very clear about getting this phone

out of people's hands.

Not only were they offering an exchange

for another Samsung phone,

or getting free credit toward another device

at carriers like AT&T and T-Mobile,

but when people were not still doing that,

they tried to break these things.

So at one point there was a software update sent

that would limit the battery to only charge it

like, 20 to 30 percent.

They were literally locked out of the network.

I mean, people were treating this like a legit bomb.

(bomb explodes)

Now Samsung were eventually able to solve the problem

by putting in a much, much smaller battery inside the Note,

and re-releasing it as the fan edition,

but the damage was very much done at that point.

Although if you're curious about what the fan edition was

and a little more about the Note 7,

we did do a full video on this a couple years ago

when this first came out.

Oh, should I get the fire extinguisher?

Just in case?

- We might need it though.

Another dangerous piece of technology is the USB killer.

Now don't let the looks fool you here.

Now sure, on the surface this looks

like a normal little USB drive,

but it has a much more nefarious purpose than that.

It will legitimately kill your laptop.

Basically, this uses a series of capacitors,

so when you pug it into a device,

it starts charging those capacitors,

and then it turns around and dumps

all that power straight back into the USB port

at like, 240 Volts,

which for a lot of systems is enough to kill them.

So it depends on what you plug it into,

and some manufacturers have gotten wise to this

and built in protections to kind of keep that power

from sort of propagating and killing everything

that it touches,

but a lot of devices it will at the very least

kill the USB port it's on,

or can even straight up kill the entire system.

In fact, recently a college student got in trouble

for using this on over 60 college campus computers,

totalling over $50,000 in damage,

and currently, because he did

so much vandalization with this thing,

he can go to prison for up to fifteen years.

Now obviously it's not illegal to use a USB killer

on your own device,

but this is straight up like killing something right?

I mean, using a USB cable and plugging it in

is no different than taking like a baseball bat

to like a laptop or something.

It can absolutely kill it jus as easily as a,

I don't know, like a fire extinguisher or a hammer,

or water.

This is a laptop that we recently had on Mystery Tech,

and Ken semi-killed it with water,

so let's see if the USB killer still has it.

I normally would feel really bad about this

because we know how powerful this is,

but this laptop is essentially half dead anyway.

So, you guys ready?

- [Cameraman] Yeah.

- [Man] A firewall is used to access a--

(click)

- It's instant man!

Oh, oh, oh okay well,

maybe not dead, but not good.

We're going to move on,

before Dangerous Tech becomes how to,

oh dude it's so warm on the bottom too.

We're gonna put this back

and continue with Mystery Tech with,

Dangerous Tech, whatever this is called.

Put yourself in 2015.

Vine is still a thing,

everyone is playing The Witcher 3,

and the Hoverboard is brand new.

Whee.

So you can imagine after a fun day

of riding your shiney new Hoverboard around,

you plug it in,

only to find that the battery starts

to smell a little bit odd.

The smoke starts to fill the room,

and you realize that your awesome new toy

is on fire!

So back when they first started coming out,

there were a flood of different clones on the market.

And some of them were completely safe and completely fun,
