00:00I'm in my Tesla on autopilot going 40 miles an hour towards a fake Wily and Coyote Roadrunner painted wall.
00:06Please stop. Please stop.
00:08And 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
00:21to 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
00:32started 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, as 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!
00:5443 million people ride Space Mountain every year.
00:58But unlike a famous ride like Colossus, Space Mountain is in near total darkness,
01:04meaning no one knows what the ride actually looks like, which as far as I'm concerned, needed to be fixed with a special undercover operation.
01:12True story, I had 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, someday the technology will be there,
01:22so we could map out what Space Mountain actually looks like.
01:25So, this is a very big moment for me.
01:27Now, as 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.
01:37And if I managed to do that, step two would be making it through the park, avoiding any security guards on my way to Space Mountain.
01:43And finally, for step three, I would need to sneak onto the ride itself, while 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.
01:58How are you, man? Why are you doing this to me?
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, I 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.
02:18Do you want this?
02:20Well, just wait until your bag is feeling free, in case you have a plan that you don't slide over here.
02:25And even though this moment of truth was terrifying, I knew I just needed to play it cool.
02:29Like that.
02:30Excuse me, can you not record?
02:32And the security was, in fact, extremely tight.
02:35But our alibi was tighter.
02:37Alright, we're in. One down, two to go.
02:39Once 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 problems.
02:48The park security.
02:49Which 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.
02:58So in an attempt to blend in and look like a normal park goer, I took a corn dog break.
03:03We're doing this for the integrity of the mission.
03:06We're the best to live!
03:08Not because we're incredibly vicious.
03:10Back on track after a close call or two, I had made it inside the building.
03:14Alright, two down, now for the hard part.
03:16Now that we're inside, it's probably a good time to explain why my jacket looks like this when you view it with an infrared camera.
03:22Because that is a really tiny portable LiDAR scanner.
03:25So it's shooting out 640,000 laser pulses per second to fully map the surroundings.
03:30Now as for the legality of this, if you check the back of your ticket, it says you have to obey all the park rules.
03:36And if you check their website for the rules on forbidden items, it 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 by 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 watching 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, as you can see here,
04:16not 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 shooting all around the room.
04:31And each time you fire one of them, you then see how long it takes for 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, it 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 firing all out at once?
04:53Well, it turns out, amazingly, they actually happen one after another.
04:57So 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, if you slow time way down,
05:04so the time it takes a laser to hit an object is 4 slo-mo seconds,
05:07then you can wait 30 minutes on that slo-mo time scale before sending the next pulse.
05:13So it's actually really easy for the sensor to know exactly 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 of Secret Undercover Operation Mousetrap.
05:27Let's go!
05:29Woo-hoo-hoo-hoo!
05:34Yeah!
05:36It felt so good to cross off a 30-year-old bucket list item.
05:40Yeah!
05:42Oh!
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.
05:50All flights have been put in a holding back.
05:52Stopped 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 treat come true.
06:06Before I even have a YouTube channel, I wanted to do that.
06:09And the only critical oversight of the whole operation was forgetting
06:12they 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.
06:41Now what'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.
06:50But 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.
06:58Which meant for the first time ever, this question mark stays,
07:01we're numbered.
07:02Got it.
07:07So while all the 3D printers were hard at work,
07:09we also reviewed the data we captured from the Haunted Mansion ride.
07:12Where we made two super interesting discoveries.
07:14The first is that the initial room they take you in is really just a fancy elevator
07:18so they can get you underground to transport you to the real ride,
07:21which actually isn't in this house at all.
07:23Because when you go down this hallway, you're walking under this hill you see here.
07:27So by the time you load onto the ride, you're totally outside the park.
07:31But if that's true, there should be some evidence for this besides our scan.
07:34And sure enough, there is.
07:36Because if you look back at this shot of the hill,
07:38you 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 where the ride actually takes place
07:48that matches up perfectly with our lidar scan.
07:51Which is just super clever engineering by the super talented Disney Imagineers.
07:56And the second discovery is they use a lot of super thin, nearly 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.
08:09And so you can imagine, there are some incredible real-world applications for this lidar technology.
08:15Like every day when your phone scans your face to unlock itself,
08:18or when archaeologists use it to find lost ancient cities from the sky,
08:22or for example,
08:27in cars.
08:28And as you might have guessed, this car automatically saved itself from crashing
08:31because it uses a lidar sensor, which as you can imagine,
08:33would have saved Wile E. Coyote a lot of pain over the years.
08:39And the reason it works so well is because it's updating that point cloud of 640,000 laser measurements
08:44every second to the brain of this car showing exactly what's in front of it.
08:48In fact, it works so well, as you can see here,
08:50I can maneuver all around these obstacles in real time with all the windows blacked out,
08:55looking just at that point cloud in a VR headset.
08:59Okay, easy bike guy.
09:00My Tesla on autopilot, however, only relies on simple cameras and its image processing to 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 head-to-head face-off,
09:11culminating in a history-making first Tesla versus cartoon physics test.
09:16Okay, so we're starting out with the car with the lidar.
09:19First test is just kids standing in the road.
09:21Not sure why he's doing that.
09:22It's very unsafe.
09:23So we want to be extra careful.
09:25Okay, hit it.
09:26The testing speed was 40 miles an hour.
09:28Should've put my seatbelt on.
09:29Which 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.
09:37Now 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.
09:53Just not in time to fully hit the brakes.
10:00Oh no.
10:01He was even a Crunch Labs fan.
10:04Now if you're a Tesla owner, there is a silver lining.
10:07Because we were relying on the automatic emergency braking system to stop for the car.
10:12And because it assumes the driver's paying full attention while fully driving the car,
10:15it only hits the brakes when it's 100% sure there's a problem in order to avoid false positives.
10:20So the alternative is to use autopilot.
10:23And that assumes the driver isn't paying much attention.
10:25And while the downside is you get way more phantom braking and false positives.
10:29Oh, that was ridiculous.
10:32The upside is you're less likely to be charged with vehicular manslaughter.
10:36Because you can see here on autopilot, it actually stopped in time.
10:39So I decided to be nice and call the score one to one.
10:42And then I'd be even nicer by using the more conservative autopilot on the Tesla for all the remaining tests.
10:48Such as this one, where we would now simulate the kid dashing out from behind a pirate car using some clever engineering.
10:53Giving the cars less than a second to identify the mannequin and stop themselves.
10:57Here we go.
10:58Getting up to speed.
10:59Oh, a ball came out.
11:01I wonder why that happened.
11:02Oh, kid.
11:04Another life saved.
11:08Now it was the Tesla's turn on autopilot.
11:1040 miles an hour.
11:11There 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, I can no longer see that there's a kid through this fog.
11:27The LiDAR has no issue.
11:29This will be interesting.
11:31Okay, here we go.
11:32Oh, wall of fog.
11:33So we plunge through the fog, coming to a very sudden break.
11:37Hey!
11:38After which we saw the mannequin was not only still standing, but it was casting a really
11:43cool long shadow, because the lasers don't pass through solid objects.
11:47Just like how you can cast a long shadow with the sun, because light doesn't pass through
11:52solid objects.
11:53I don't have high hopes here.
11:54But would the kid look just as cool after the Tesla test?
11:57Oh, oh, oh, fudge!
11:59Oh, ho, ho, ho, ho, ho, ho, ho, ho.
12:02I mean, Volvo does make everything look sort of cool.
12:06But that wasn't the only shot.
12:07I actually hit the brakes there.
12:09That was on autopilot.
12:11The 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.
12:21Time to make it rain!
12:24The next test would see if the cars could spot the kid under a torrential downpour made up,
12:28or maybe too much water.
12:30This is really interesting.
12:32See, the Tesla can see the kid, but as soon as it starts raining, the kid is gone.
12:37And it was similar in the LiDAR car, where you first got a clear image of the kid and the shadow.
12:42Once we started the hose, oh, you see all the water going in.
12:45LiDAR might struggle here.
12:46Okay, here we go.
12:47And as the wall of water started, LiDAR seemed to not slow down at all.
12:51Until the last possible second.
12:57Another W!
12:58Now I just need the rain to stop.
13:00Do you know any good rain dances?
13:02Can I just back up?
13:03Oh, that's actually a good idea.
13:05Now that LiDAR had surprised me, it was time to see if Tesla could as well.
13:09Oh boy.
13:10Oh boy.
13:11And sadly, it did not.
13:17And though I did everything I could.
13:19Yeah, he's no longer with us.
13:21So it was on to the penultimate round five, where we had six of the brightest lights that
13:25money could buy simulate either sunset or sunrise, or 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.
13:34Let'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.
13:41Question remained if it would see the kid.
13:43Come on, LiDAR.
13:44Oh!
13:45And it did it.
13:47No problem.
13:48It just always waits until the last minute.
13:50It gets me every time.
13:52That's very bright.
13:53Time to be blinded by the light.
13:55Blinded by the light.
13:57And it's true.
13:58These lights were so bright, I wouldn't have seen this kid on my own.
14:01And at this point, I really doubted that the Tesla could either.
14:04But when it pulled to a stop.
14:06Okay.
14:07We stopped for the kid with the bright lights.
14:09A W for the Tesla.
14:11And that W meant these were the scores headed into the painted brick wall ultimate grand finale.
14:16Scientific papers have actually been written on this exact scenario.
14:19Debating theoretically what the Tesla would do.
14:21But we were here once and for all to silence all the debates with cold hard data.
14:26Alright, so LiDAR is perfect and Tesla is 3 for 5.
14:29But as far as I'm concerned at this point, this one's the only one that matters.
14:33Oh my gosh.
14:34I can't believe I'm going to do this.
14:36Alright, hit it.
14:38Now as you can see as a human driver, while that looks sort of convincing, the image processing in our brains is advanced enough that we pick up on minor visual inconsistencies and we wouldn't hit it.
14:47And as for the LiDAR, it isn't looking at what image is printed on the wall.
14:50So this sort of just looks like a wall, which would make this the easiest test of the day.
14:54And as I suspected, handled it with no problem.
14:58So the question was, would the Tesla detect and stop for this Wile E. Coyote style painted wall that was hiding yet another child staring at nothing during what might be his last minutes on earth?
15:08One way to test that hypothesis.
15:10I was actually supposed to go, but I chickened out.
15:13The car may not know it's a wall, but I know it's a wall.
15:19Everything in your body says, don't drive into a wall.
15:22Oh boy.
15:24Alright, here we go.
15:25And so I steeled myself and accelerated the Tesla up to the 40 miles an hour.
15:30And as the wall crept closer and closer without moving an inch.
15:34The question was if the Tesla would detect it in time to step on the brakes.
15:38And it turned out.
15:39Ouch.
15:40Holy me.
15:41So I can definitively say for the first time in the history of the world, Tesla's optical camera system would absolutely smash through a fake wall without even a slight tap on the brakes.
16:00My heart is gonna beat out of my chest.
16:06Turns out my Tesla's more Wile E. Coyote and less Road Runner.
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 the superior car technology, could it actually deliver on the dream of 14 year old Mark Rober and map out Space Mountain well enough for me to make a scaled 3D printed model.
16:29And after 30 years of waiting, I'm happy to report for the first time ever, this is what the Space Mountain track actually looks like.
16:36Whoa.
16:37This is so cool.
16:40Oh, there's me.
16:41There's me.
16:42Little backwards hat.
16:43Yeah.
16:44I recognize every single one of these turns.
16:50You go up right there.
16:51Then you come down.
16:53And then it's all the right turns, right turns, right turns.
16:58Right here is where they take your picture.
17:01This is wild.
17:0314 year old me would be so proud right now.
17:06This is it.
17:07Space Mountain has been revealed.
17:09And thanks to Harrison's mapping technology, this means you can now actually see what it would look like to ride Space Mountain with all the lights on in Crunch Labs.
17:17Even if at this size, you'd be way below the ride's five foot minimum height requirement.
17:22And all of this is why I love being an engineer.
17:25You get to shape the future, potentially save a bunch of lives, and accomplish even the most ridiculous 30 year life goals.
17:35If you're a teenager or adult and you've always wanted to make and build cool stuff, but just haven't figured out that first step, this is it.
17:42It's called the Crunch Labs Hack Pack.
17:44And it's basically a series of really fun programmable robots that get delivered right to your door where we build it together and learn step by step the kinds of engineering skills that go into making the builds on my YouTube channel.
17:55And they all work with no programming required.
17:57But since my goal is to take you from wherever you're at and level you up, you can easily hack the microcontroller brains of any of these robots in a bunch of ways to completely level up the functionality.
18:07There's also a community where you can share your builds or post questions, as well as an AI chatbot named Mark Robot that will check your code for you and help you implement your most creative ideas.
18:17On top of all that, each box has a chance to contain a platinum diploma.
18:21And if your box has it, congratulations, because college is now free for you or a loved one you want to transfer it to.
18:27Plus, you get to come out here and brainstorm one of your own ideas with me and my team for a day.
18:31So if you want to enhance or even just take the first step of unlocking the really fun and rewarding hobby of making stuff, just go to crunchlabs.com or use the link in the video description.
18:40Where to say thank you, we're giving away that free box as an early subscriber special.
18:44Thanks for watching.
