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.
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.
Why would children be interested in car safety?
Why would children be interested in anything?
Have you never seen educational content before that wraps up potentially boring teachings in an exciting narrative?
Since most grownups aren’t interested in safety, I just thought it would be even less for kids.
All sales promotion stats show that car buyers basically don’t care about safety features. Almost all significant safety features are there because of regulation.
Edit:
I can only laugh at the downvoters, you know nothing. It’s been a well established fact that safety doesn’t sell cars since the 50’s.
Seems like a strange application of stats when, as you say, the regulated safety features - the important ones - need not come into a decision-making process and advertising them would be a waste of time.
Stats made over decades back in 50-70’s
So… out of date stats about advertising?
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.
Cool inquisitive kid you have there. 👍 😀
Who downvoted this? XD This brings me joy
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.
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.
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.
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.
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.
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.
And what is this “algorithm” based on? Actual user behavior. So the way to correct an algorithm is to change actual user behavior, no?
Lemme know when they release an OTA for our parietal lobes.
No one knows.
Definitely not. I pretty much exclusively get recommended garbage content, and 90% of it is already on the “trending” page. At least it was like 3 years ago before I stopped using any of YTs first-party front-ends.
I must say that the recommendation section on youtube for me is spot on! Though I spent years on youtube constantly liking and disliking content. But I think it learned me quite well.
When im tired of recommendations I move to subscriptions. And 5 hours just passed by…
Have you heard of DeArrow? https://dearrow.ajay.app/
It’s a browser extension that replaces clickbait thumbnails with good community sourced ones
Thanks no I hadn’t. Is that available as a Firefox extension. I do most of my browsing on desktop.
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.”
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:
I give you a green round ball. You then proceed to ask me the colour and shape of the ball.
The link in a comment that wasn’t for me? Like I update every 10 minutes to read all the comments??
Get real will you.
The link you replied to.
The link is right there, you could’ve just clicked it instead of taking the time to write this question?!
OK I see it now, a bunch of icons I usually glance over, because such “icon lines” are generally for a bunch of social media crap I don’t use.
Apparently it’s proprietary crap, so no thanks anyway.

This (again) is from the link in the comment you replied to…
Your attitude really doesn’t work well with your lack of reading comprehension.
6 hour trial, sounds like proprietary to me.
Edit: I just read the entire text, and it is actually very reasonable, I just caught the license key thing together with the payment option. It’s actually even cheap, so maybe I’ll consider it.
You cannot be serious?! Are you trolling?
First of all, something not being free (as in gratis) does not mean it is proprietary per se.
Second of all, your reading comprehension failed you again:
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.
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.
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.
Doesn’t address the point that humans would be equally deceived by this wall if they don’t pay 100% attention.
With this paint job, in this environment? Maybe. Though IRL you would probably see it much clearer due to the lack of parallax effect on a 2D projection.
But if we’re talking e.g. about a dark-ish barrier at knee height, your brain does a much better job to quickly recognize it as obstacle. Whereas cameras without depth perception would fail completely.
At this point everyone should know that YouTube thumbnails have no requirement for accuracy. It’s more like an album cover.
I know, but if they are about anything serious like tests, I think it’s a fair assumption that the thumbnail represent it reasonably.
If it’s misleading, I don’t want their vomit. They can just fuck right off. We already have more than enough misinformation. I simply don’t want to waste my time on bullshit.
