Mark Rober just set up one of the most interesting self-driving tests of 2025, and he did it by imitating Looney Tunes. The former NASA engineer and current YouTube mad scientist recreated the classic gag where Wile E. Coyote paints a tunnel onto a wall to fool the Road Runner.

Only this time, the test subject wasn’t a cartoon bird… it was a self-driving Tesla Model Y.

The result? A full-speed, 40 MPH impact straight into the wall. Watch the video and tell us what you think!

This is a very good test, and the car should have past. That said though, I hate the click bait format where they show a stupidly obvious cartoonish wall, when the real wall is way more convincing.

The Video:

That sort of clickbait is 100% sure to get a "do not recommend channel" from me, I'm so sick of it. And it's sad when the video has such a good point.

The Clickbait

I can see it's kind of funny, but it's misleading.

YouTubers - especially large channels like this - constantly A/B test with different thumbnails and stick with whatever one drives the most traffic (no pun intended) to the video.

You might not like it, but it’s unfortunately the reality of operating a content creation business on an algorithm-driven platform.

There are plenty of channels I follow that make fantastic videos, but sometimes you have to tolerate the shitty thumbnails because that’s just the reality of the system they’re operating within.

[–] [email protected] 15 points 6 days ago

Yeah, that is just how youtube works. You as an individual can say you don't like annoying thumbnails and titles, but they 100% work. And channels that don't use them are just not getting as many viewers.

Have you heard of DeArrow? https://dearrow.ajay.app/

It's a browser extension that replaces clickbait thumbnails with good community sourced ones

Still supports a creator pulling clickbait.
The only way is to vote with views/retention.

[–] [email protected] 13 points 6 days ago (1 children)

But it only supports them if their video is then also good. I don't like clickbait, because I don't want to be tricked into my monkey brain looking at something. I do want to see good videos.

Just yesterday the algorithm found some guy doing tech videos. I watched a few of them and then sent a text to a friend who I thought would like it. He asked for a link so I pulled the guys channel up on my phone, and holy smokes, clickbait. If I hadn't seen the videos already I wouldn't have given that guy the time of day. But they are well thought out, interesting videos.

I'm not here to correct the world's poor behaviour. I'm here to watch good videos. De-arrow does a good job of that, it's quite interesting to see YouTube on a computer without it vs what I'm used to now.

[–] [email protected] 12 points 6 days ago (1 children)

Blame the youtube algorithm and Mr Beast, not all the other youtubers caught up in the tidal wave.

[–] [email protected] 10 points 6 days ago

Yeah they do it because it works. I've seen several who make otherwise good content talk about it in their videos and make comments about how stupid it is bit they basically have to to be competitive.

[–] [email protected] 6 points 6 days ago

Want to guess why they are there in the first place?

I hate it too, but it’s mostly one of those “we can’t have nice things because of other people around us” situations.

[–] [email protected] 7 points 6 days ago (2 children)

Thanks no I hadn't. Is that available as a Firefox extension. I do most of my browsing on desktop.

[–] [email protected] 24 points 6 days ago (6 children)

The link is right there, you could've just clicked it instead of taking the time to write this question?!

Yes, but you could have just clicked the link to find that out

Imagine being in the middle of a friendly conversation where you ask a question and the person says, "Why are you asking me?? Just google it."

[–] [email protected] 12 points 6 days ago (1 children)

Well, this is a forum, not an out-loud discussion, so those are 2 completely different scenarios

They were also already given the link, so I guess:

Imagine being in the middle of a friendly conversation where someone asks for something, you give it to them, and then they proceed to ask questions about it that could be answered by looking at the thing you gave them

[–] [email protected] 6 points 6 days ago

I give you a green round ball. You then proceed to ask me the colour and shape of the ball.

[–] [email protected] 8 points 6 days ago

I'm not the OP, so I wasn't having a conversation with them. But to me it gives off the vibe of "Random stranger, you should do all the work for me and provide all the answers, because I'm too lazy to do any of it myself."

Could just be me though 🤷

You realize Mark Robers target audience is like 8 years old, right? He also references looney tunes and wile e coyote a couple dozen times, including in this thumbnail you're losing your mind over. The thumbnail fits the theme very well if you ask me.

This video isn't a rigorous scientific test. This is a children's video designed to get them interested in the scientific method. Get over yourself.

[–] [email protected] 9 points 6 days ago (1 children)

IMO it doesn't need to be a rigorous scientific test, it's not trying to prove something works as it should under all conditions. It's showing the exact opposite, it does not work under this one condition, which is more than enough to disprove the safety of the car.

[–] [email protected] 4 points 6 days ago

More than one test failed.

The Tesla failed the heavy rain and the heavy fog tests.

There's zero excuse to fail either of those tests. But the Tesla killed the kid both times.

The wall test was just to show that the Tesla cannot put together optical clues.

[–] [email protected] 5 points 6 days ago (7 children)

Why would children be interested in car safety?

[–] [email protected] 28 points 6 days ago (1 children)

My 6 year old kid loves anything about car and enjoyed Marks video. While driving him from school, he asked me why we can tell it's a wall but the cars can't. It sparked a 20 minutes discussion on car safety and why we need seat belts.

[–] [email protected] 13 points 6 days ago (1 children)

Cool inquisitive kid you have there. 👍 😀

Have you never seen educational content before that wraps up potentially boring teachings in an exciting narrative?

Why is anyone interested in anything?

My nephew was obsessed with Teslas a few years ago. I asked him why, his response? The indicators can be set to make fart noises.

My 7 year old daughter and I watch Mark's videos together and they have helped to spark her interest in engineering & science.

[–] [email protected] 9 points 6 days ago (1 children)

Oh wow, you really didn't realize? Yeah man this is a youtube channel for getting kids interested in science and technology, like the technology surrounding self driving cars and lidar. Did you see the part where he introduced the technology by taking it to Disney world?

Here's a random video from crunchlabs, the company he created and advertises on ALL of his videos. This video shows his fan base enjoying what they got from crunchlabs.

That's cool then, but probably not for me. And I still think it's misleading. If they made the analogy in the video it would be different. But as it is, it looks like clickbait. And honestly using clickbait on children is actually worse.

At this point everyone should know that YouTube thumbnails have no requirement for accuracy. It's more like an album cover.

Still astounded people use anything other than the subscription section on YouTube.

History turned off, subscriptions only for me.

We are in a tiny, tiny minority.

I disagree with this being a good test. Where on earth would you find a wall on a road with a fotorealistic continuation of the road printed on it? This would trick many human drivers. Self driving cars fail in many realistic situations that are a lot more concerning. This is just clickbait.

[–] [email protected] 34 points 6 days ago

True, but Mark's video basically about comparing Tesla's Camera Sensors Vs Self Driving car with a Lidar Sensor.

They also simulated some real life scenarios which the car with Lidar sensors passed easily, while Tesla failed some of them.

So I guess Lidar sensors are superior compared to Teslas cameras.

[–] [email protected] 26 points 6 days ago

Where on earth would you find a wall on a road with a fotorealistic continuation of the road printed on it?

Spoken like a man who has never relentlessly pursued a roadrunner, nor taken a wrong turn at Albuquerque.

[–] [email protected] 8 points 6 days ago* (last edited 6 days ago) (3 children)

You haven't seen what Teslas are in the news for lately?

It's not that crazy someone would put up a fake wall on some backroad to catch out inattentive Tesla drivers. Doesn't even need to be nearly as big and elaborate as this one. Any painted object would accomplish the same.

But the point of the video is that optical cameras are easily deceived, and Elon is lying to his customers that LiDAR is overrated and not necessary.

This YT channel definitely went all out on the cartoonish nature of this particular test, but the article describes other tests as well including running over mannequins representing children that other cars (Lexus) avoided.

[–] [email protected] 4 points 6 days ago

While I agree that this would trick many human drivers, I think the goal of a self-driving car is that it be better than human drivers. And there is existing tech that could help achieve that.

Well if your thumbnail is not good enough and catchy people will not watch it. Which wont make the channel profitable. Which will cause it to not exist.

I hope you know that usually youtubers will not even start making the video if they don’t have a killer thumbnail to it. Thats the platform.

[–] [email protected] 4 points 6 days ago (1 children)

passed

I agree with everything you said.

[–] [email protected] 3 points 6 days ago (1 children)

Thanks. 😎
Then imagine why 15% downvote? I suppose it means they don't see how it's misleading?

[–] [email protected] 3 points 6 days ago

YouTube is always click bait nowadays. There are plenty of that aren't and have good quality. But everyone I encounter that's trying to breakout is sensational for the sake of being sensational.

That's more a product if the yt algorithm. For every one like you that is annoyed by the clickbait, there are a million others instantly clicking with no further thought. So if you don't do that, you're losing money.
