SpaßTranskript
00:00I'm in my Tesla on autopilot going 40 miles an hour towards a fake Wiley-Car-Owning-Roadrunner-Painted-Wall.
00:06Please stop. Please stop. Holy...
00:09And I'm doing this to see if Tesla's autopilot can be tricked.
00:12Because it famously only relies on simple cameras to navigate the world, as opposed to much more expensive tech.
00:18In fact, we're out here today to run a bunch of tests in extreme conditions
00:22to see how those simple cameras on a Tesla stack up against other fancy cars that use more advanced technology.
00:28Wow!
00:29And the story of how I ended up as a crash test dummy in my own car
00:34started six months back at Disneyland, as I was sneaking onto the famously pitch-black ride called Space Mountain.
00:40And while I might look a little plus-sized in that jacket,
00:43as you can see from this infrared camera shot,
00:46that's no ordinary jacket, because it's hiding some of that fancy car technology.
00:51Yeah, baby!
00:54Yeah!
00:5643 million people ride Space Mountain every year.
00:59But unlike a famous ride like Colossus, Space Mountain is in near total darkness.
01:04Meaning no one knows what the ride actually looks like.
01:08Which, as far as I'm concerned, needed to be fixed with a special undercover operation.
01:13True story, I have been wanting to make this video for over 20 years, way before I had a YouTube channel.
01:18Because I would come to Disneyland and just be like,
01:20Someday the technology will be there, so we can map out what Space Mountain actually looks like.
01:25So, this is a very big moment for me.
01:27That's common knowledge. Every good undercover operation worth its salt needs a three-step plan.
01:32For me, step one would just be getting into Disneyland with my tech through their famously tight security.
01:37If I managed to do that, step two would be making it through the park,
01:40avoiding any security guards on my way to Space Mountain.
01:43And finally, for step three, I would need to sneak onto the ride itself,
01:47while avoiding any suspicion to make my childhood dream come true.
01:50And if all this seems like overkill, let's just say I have a bit of history
01:55getting kicked out of amusement parks in the name of science.
02:00For step one, I took an oversized jacket and made a little pocket inside where I could hide my secret tech inside it.
02:06It's like the slight limp shuffle lock that really sells it, I think.
02:09Because they make you walk through metal detectors,
02:11I disguised and temporarily placed my device with a bunch of gear in my camera bag.
02:15And just had to hope it wouldn't get discovered.
02:25And even though this moment of truth was terrifying, I knew I just needed to play it cool.
02:30Like that.
02:32And the security was, in fact, extremely tight.
02:35But our alibi was tighter.
02:40Once inside, I immediately made my way to a bathroom to properly suit up.
02:43Now I just had to make it all the way over to Space Mountain without arousing the suspicion of any of the park security.
02:48Which is a lot harder than you might think, because it's a well-kept secret.
02:51Disney employs a bunch of security officers dressed up in plain clothes as normal park goers.
02:56So I could trust no one.
02:59So in an attempt to blend in and look like a normal park goer, I took a corndog break.
03:03Back on track after a close call or two, I had made it inside the building.
03:11Now that we're inside, it's probably a good time to explain why my jacket looks like this
03:14when you view it with an infrared camera.
03:16Because that is a really tiny portable LiDAR scanner.
03:19So it's shooting out 640,000 laser pulses per second to fully map the surroundings.
03:24Now as for the legality of this, if you check the back of the jacket,
03:27you can see that there's a lot of laser pulses.
03:30Now as for the legality of this, if you check the back of your ticket,
03:33it says you have to obey all the park rules.
03:36And if you check their website for the rules on forbidden items,
03:38it says you can't bring in shoes with wheels, or stun guns, or cremated remains.
03:43Ew.
03:44But you'll notice the forbidden items list makes no mention of chest-mounted LiDAR scanners.
03:49So technically, I'm not breaking any laws
03:51by precisely mapping out this entire ride down to the nearest half inch.
03:56Don't blow this, Rover! We got this!
03:58And so after sneaking past the last of the ride's security, I was finally in place.
04:02And this is probably a good time to point out that the final boss here in this control room
04:05watching all the infrared see-in-the-dark cameras
04:08was the one I was most afraid would shut down the whole operation.
04:11Because when we tested this out to see how inconspicuous the LiDAR would be,
04:15as you can see here, not very,
04:17as it lights up the whole place like a Christmas tree.
04:20By the way, you should know LiDAR stands for Light Detection and Ranging,
04:23whereas radar is Radio Detection and Ranging.
04:26Basically, it's like having a bunch of laser pointers inside this shell
04:29shooting all around the room.
04:31And each time you fire one of them, you then see how long it takes
04:34for you to see it hit the object it's pointed at.
04:36And since we know the speed of light, if we measure that time,
04:39it will tell us how far away the object is.
04:41For example, it will take twice as long to detect the laser point on an object that's 20 feet away
04:45as opposed to an object that's 10 feet away.
04:47But how could the sensor possibly keep track of 640,000 laser pulses
04:51firing all out at once?
04:53Well, it turns out, amazingly, they actually happen one after another.
04:56So the sensor only has to keep track of one pulse at a time.
05:00And this works because the speed of light is so fast, in fact.
05:03If you slow time way down, so the time it takes a laser to hit an object
05:06is four slow-mo seconds, then you can wait 30 minutes
05:09on that slow-mo time scale before sending the next pulse.
05:13So it's actually really easy for the sensor to know
05:16exactly which laser pulse it's measuring,
05:18even if that happens 640,000 times in a single second.
05:22And with that, it was time for the execution phase
05:24of Secret Undercover Operation Mousetrap.
05:36It felt so good to cross off a 30-year-old bucket list item.
05:43But just as I feared, as our exact cart pulled back into the station,
05:47they stopped the ride and announced it was being locked down.
05:52They stopped the ride.
05:53Which meant I was about to have an unscheduled appointment
05:55with a bunch of dudes with muscles much bigger than mine.
05:59But as it turns out, it was an unrelated power issue,
06:02which meant this was a mission accomplished.
06:04That's like a dream come true.
06:06Before I even had a YouTube channel, I wanted to do that.
06:09And the only critical oversight of the whole operation
06:11was forgetting they took those dumb keychain photos at the end of the ride,
06:15leaving behind some very incriminating evidence at the scene.
06:18I forgot to put it away.
06:19That's so awesome.
06:20That's Harrison, by the way.
06:22And he started the company that makes these super small portable lidars.
06:25After mapping out a few more rides like Haunted Mansion,
06:27Let's go!
06:29and continuing my painstaking efforts to blend in,
06:32we headed home so Harrison could process all the data.
06:34And a few days later, he did not disappoint.
06:37This is from the lidar you were wearing on your chest.
06:39Get out of here.
06:40All of this is totally in the dark.
06:42What's really cool is we can visualize what was recorded as the ride progresses.
06:45And so as you can see here, you get a sense of what the lidar was seeing in real time
06:49as the ride progressed on.
06:51But what's even cooler, though, is we can now use that data
06:53to make an actual tabletop 3D model of Space Mountain
06:56with the help of our army of 3D printers.
06:59Which meant for the first time ever, this question mark's days were numbered.
07:07Got it.
07:08So while all the 3D printers were hard at work,
07:10I wanted to show you the data we captured from the Haunted Mansion ride,
07:12where we made two super interesting discoveries.
07:15The first is that the initial room they take you in
07:17is really just a fancy elevator,
07:19so they can get you underground to transport you to the real ride,
07:22which actually isn't in this house at all.
07:24Because when you go down this hallway,
07:26you're walking under this hill you see here.
07:28So by the time you load onto the ride,
07:30you're totally outside the park.
07:32But if that's true, there should be some evidence for this besides our scan.
07:35And sure enough, there is.
07:37Because if you look back at this shot of the hill,
07:39you can actually see just the corner of some kind of large building.
07:42And if you check that answer on Google Maps,
07:44you can see this entire massive above-ground warehouse
07:47where the ride actually takes place
07:49that matches up perfectly with our LiDAR scan.
07:52Which is just super clever engineering
07:54by the super talented Disney Imagineers.
07:56And the second discovery is they use a lot of super thin,
07:59nearly invisible curtains they project on
08:01that create a lot of the illusions like these flying ghosts.
08:04And while your eye might get fooled, as you can see here,
08:07there's no hiding from the LiDAR scan.
08:11And so you can imagine, there are some incredible real-world applications
08:14for this LiDAR technology.
08:16Like every day when your phone scans your face to unlock itself,
08:19or when archaeologists use it to find lost ancient cities from the sky,
08:23or, for example,
08:27in cars.
08:28And as you might have guessed,
08:29this car automatically saved itself from crashing
08:31because it uses a LiDAR sensor,
08:33which, as you can imagine,
08:34would have saved Wile E. Coyote a lot of pain over the years.
08:39And the reason it works so well
08:40is because it's updating that point cloud
08:42of 640,000 laser measurements every second
08:45to the brain of this car,
08:46showing exactly what's in front of it.
08:48In fact, it works so well, as you can see here,
08:51I can maneuver all around these obstacles in real time
08:54with all the windows blacked out,
08:56looking just at that point cloud in a VR headset.
08:59That easy bike guy.
09:00My Tesla on autopilot, however,
09:02only relies on simple cameras and its image processing
09:05to navigate the world.
09:06So to see if that tech is just too simple,
09:08we came up with a six-part LiDAR versus camera
09:10head-to-head face-off,
09:11culminating in a history-making first
09:13Tesla versus cartoon physics test.
09:16Okay, so we're starting out with a car with the LiDAR.
09:19First test is this kid standing in the road.
09:21Not sure why he's doing that.
09:22It's very unsafe, so we want to be extra careful.
09:24Okay, I hit it.
09:25The testing speed was 40 miles an hour,
09:28which meant the LiDAR would have to detect the kid
09:31and then slam on the brakes at least 60 feet in front of him.
09:34And it turned out, that's all it needed.
09:39Now it was Tesla's turn.
09:40This is a terrible feeling driving straight at a kid,
09:43but this is for science.
09:45All right, we are up to speed.
09:47And with just simple cameras, the Tesla was speeding fast.
09:50Oh, no.
09:51But did detect the kid.
09:58Just not in time to fully hit the brakes.
10:00Oh, no.
10:02He was even a Crunchlads fan.
10:05Now, if you're a Tesla owner, there is a silver lining,
10:08because we were relying on the automatic emergency braking system
10:12to stop for the car.
10:13And because it assumes the driver is paying full attention
10:15while fully driving the car,
10:16it only hits the brakes when it's 100% sure there's a problem
10:19in order to avoid false positives.
10:21So the alternative is to use autopilot.
10:23And that assumes the driver isn't paying much attention.
10:26And while the downside is you get way more phantom braking
10:29than false positives.
10:32That was ridiculous.
10:33The upside is you're less likely to be charged with vehicular manslaughter.
10:37Because you can see here on autopilot, it actually stopped in time.
10:40So I decided to be nice and call the score one to one.
10:43And then I'd be even nicer by using the more conservative autopilot
10:46on the Tesla for all the remaining tests,
10:49such as this one, where we would now simulate the kid
10:51dashing out from behind a parked car using some clever engineering,
10:54giving the cars less than a second to identify the mannequin
10:57and stop themselves.
10:58Here we go, getting up to speed.
11:00Oh, a ball came out. I wonder why that happened.
11:03Oh, kid!
11:07Another life saved.
11:08Now it was the Tesla's turn on autopilot.
11:1040 miles an hour, there goes the ball.
11:13And impressively, it stopped with plenty of room to spare.
11:16Good job, Tesla.
11:17Which meant we were all tied up heading into round three,
11:20the fog round.
11:21Optically, with my own eyes,
11:23I can no longer see that there's a kid through this fog.
11:27The LiDAR has no issue.
11:29This'll be interesting.
11:31Okay, here we go.
11:32Oh, wall of fog!
11:34So we plunged through the fog, coming to a very sudden break.
11:37Hey!
11:39After which we saw the mannequin was not only still standing,
11:42but it was casting a really cool long shadow,
11:45because the lasers don't pass through solid objects,
11:47just like how you can cast a long shadow with the sun,
11:50because light doesn't pass through solid objects.
11:52I don't have high hopes here.
11:54But would the kid look just as cool after the Tesla test?
11:57Oh, oh, oh, fudge!
12:02I mean, Momo does make everything look sort of cool.
12:06But that wasn't the only shock.
12:07I actually hit the brakes there.
12:09That was on autopilot?
12:12The cameras didn't even hit the brakes at all.
12:15The only thing still on is the pants.
12:18That was a bad one.
12:19And now that LiDAR had taken another W...
12:22It's time to make it rain!
12:24The next test was to see if the cars could spot the kid
12:27under a torrential downpour made up of maybe too much water.
12:31This is really interesting.
12:33See, the Tesla can see the kid,
12:35but as soon as it starts raining, the kid is gone.
12:37And it was similar in the LiDAR car,
12:39where you first got a clear image of the kid and the shadow.
12:42Once we started the hose...
12:44Oh, you see all the water going in.
12:46LiDAR might struggle here.
12:47Okay, here we go.
12:48And as the wall of water started,
12:50the car seemed to not slow down at all.
12:56Until the last possible second.
12:58Another W!
12:59Now I just need the rain to stop.
13:01You know any good rain dances?
13:03Can I just back up?
13:04That's actually a good idea.
13:06Now that LiDAR had surprised me,
13:07it was time to see if Tesla could as well.
13:10Oh boy.
13:11Oh boy.
13:16And sadly, it did not.
13:18And though I did everything I could...
13:20Yeah, he's no longer with us.
13:21So it was on to the penultimate round five,
13:23where we had six of the brightest lights that money could buy
13:26simulate either sunset or sunrise,
13:28or a truck in the road having its bright lights on.
13:30Would these lights keep the cars from detecting the kid?
13:33Blinding trucker light test, let's go.
13:35LiDAR could immediately see much more than my eyes could.
13:38When the lights turned on...
13:39Oh, that's a bright light.
13:41The question remained if it would see the kid.
13:43Oh, come on, LiDAR.
13:46And it did it, no problem.
13:48It just always waits to the last minute.
13:50It gets me every time.
13:51That's very bright.
13:53Time to be blinded by the light.
13:57And it's true.
13:58These lights were so bright,
13:59I wouldn't have seen this kid on my own.
14:01And at this point,
14:02I really doubted that the Tesla could either.
14:04But when it pulled to a stop...
14:06Okay, we stopped for the kid with the bright light.
14:09A W for the Tesla.
14:11And that W meant these were the scores
14:13headed into the painted brick wall ultimate grand finale.
14:16Scientific papers have actually been written
14:18on this exact scenario,
14:19debating theoretically what the Tesla would do.
14:22But we were here once and for all
14:23to silence all the debates with cold, hard data.
14:26All right, so LiDAR is perfect,
14:27and Tesla is three for five.
14:29But as far as I'm concerned at this point,
14:31this one's the only one that matters.
14:34Oh, my gosh.
14:35I can't believe I'm gonna do this.
14:36All right, hit it.
14:38Now, as you can see, as a human driver,
14:40while that looks sort of convincing,
14:41the image processing in our brains is advanced enough
14:43that we pick up on minor visual inconsistencies
14:46and we wouldn't hit it.
14:47As for the LiDAR,
14:48it isn't looking at what image is printed on the wall.
14:50So this sort of just looks like a wall,
14:52which would make this the easiest test of the day.
14:54And as I suspected...
14:57Handled it with no problem.
14:58So the question was, would the Tesla detect and stop
15:01for this Wile E. Coyote-style painted wall
15:03that was hiding yet another child staring at nothing
15:05during what might be his last minutes on Earth?
15:08One way to test that hypothesis.
15:11I was actually supposed to go, but I chickened out.
15:15The car may not know it's a wall,
15:17but I know it's a wall.
15:19Everything in your body says,
15:21don't drive into a wall.
15:23Oh, boy.
15:24All right, here we go.
15:25And so I steeled myself and accelerated the Tesla
15:28up to the 40 miles an hour.
15:30And as the wall crept closer and closer
15:32without moving an inch...
15:34Holy crap.
15:35The question was if the Tesla would detect it
15:37in time to step on the brakes.
15:39Ouch.
15:49So I can definitively say for the first time
15:51in the history of the world,
15:52Tesla's optical camera system would absolutely
15:55smash through a fake wall
15:57without even a slight tap on the brakes.
16:01My heart is gonna beat out of my chest.
16:06Turns out my Tesla's more Wile E. Coyote
16:09and less Roadrunner.
16:10Sorry, little fella.
16:11Looks like we lost two arms and a head.
16:13Not sure that's salvageable.
16:15I think I might Uber home.
16:17But that's not all, folks.
16:18Because while LiDAR proved itself
16:20the superior car technology,
16:21could it actually deliver on the dream
16:23of 14-year-old Mark Rober
16:25and map out Space Mountain well enough
16:27for me to make a scaled 3D-printed model?
16:29And after 30 years of waiting,
16:31I'm happy to report, for the first time ever,
16:33this is what the Space Mountain track
16:35actually looks like.
16:37Wow.
16:39This is so cool.
16:41Oh, there's me.
16:43There's me, little backwards hat.
16:45Yeah!
16:48I recognize every single one of these turns.
16:51You go up right there.
16:52Then you come down.
