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!
Honestly all the fails with the kid dummy were a way bigger deal than the wall test. The kid ones will happen a hundred times more than the wall scenario.
Some sort of radar or lidar should 100% be required on autonomous cars.
I fully agree, but sadly, investors likely care more about their cars hitting walls than hitting kids. Killing a kid or pedestrian in the US is often a very cheap fine. When my uncle was run over on a sidewalk next to his son, the police ruled it an accident and the city refused to do anything. Same thing happened when my friend was ran over in a bike lane… So killing humans is probably cheaper than hitting a wall.
Interesting that in the most consumerist nation on earth, objects have more value than people.
I think insurances will require that is it comes to self driving at least here in Europe.
Anyone with half a brain could tell you plain cameras is a non-starter. This is nearly a Juicero level blunder. Tesla is not a serious car company nor tech company. If markets were rational it would have been the end for Tesla.
If markets were rational, CEO compensation would never have grown so high, and there’d be no billionaires either.
Austin should just pull the permits until all the taxis have lidar installed and tested. Or write a bill that fines the manufacturer $100 billion for any self driving car that kills a person and puts the proceeds 50% to the family and 50% to infrastructure. One of the first rules of robotics was always about not harming humans.

+1…a classic!
I love that one of the largest YouTubers is the one that did this. Surely, somebody near our federal government will throw a hissy fit if he hears about this but Mark’s audience is ginormous
Honestly I think Mark should be more scared of Disney coming after him for mapping out their space mountain ride.
He probably just made Disney admissions and security even more annoying for everyone else.
Judging by the fact that he has an imagineer-video out (effectively) at the same time as the space-mountain mapping, I’d expect that Disney was fully aware of what he was doing, and the whole sneaky-thing was just to make it more appealing to viewers.
It got fucking wile e coyoted
The scientists in Ireland calling their data set to prevent this exact fucking thing “Coyote” sent me over the moon.
Yep, I could see someone placing a billboard like that with a cliff behind it.
Clearly we don’t need lidar!

“But humans can do it with their eyes!” - says the man not selling a human brain to go with the optical sensors
“But humans can do it with their eyes!”
That’s the best part, they kinda can’t.
There are videos from before they pulled the sensors of some pretty cool stuff where teslas slammed the breaks before anything visibly happened, based on lidar sensors sensing trouble a couple cars up the road, completely blocked to vision.super cool safety tech, and then they pulled it…
one example here https://www.youtube.com/watch?v=BIcC2ZMePKI
Pretty sure that wasn’t even lidar. It was radar which is even cheaper and pretty much every other new car has if they don’t have lidar.
Don’t give him ideas!!!
On the internet, nobody knows you’re just a brain in a
jarcar.
The thing is, yes humans can do it with their eyes. But even with the giant amount of progressing power from the brain they are still not great at it.
So of the ultimate goal is to the minimum/cheapest to be almost as good as human then yes, optical sensors only are enough.
Of the goal is to prevent deaths and significantly reduce the number of accidents compared to then lidar is the best option.
Very interesting!
What’s the payoff period, I wonder, assuming everyone could afford optical only before everyone could afford better tech.
“But humans can do it with their eyes!”
The thing is, RADAR can see things humans can’t. There was a whole article a while back about a Model X that avoided an otherwise unavoidable accident by bouncing radar under the car in front of it and seeing that car slam on the brakes.
I will point out that if you (or your camera-only driver assist) can’t stop without hitting the car in front of you when they slam on the breaks, then you’re driving too close to them… You really shouldn’t ever put yourself in a position where the person in front of you could cause you to unavoidably hit them.
That said… Yeah, radar/lidar are far better than camera alone and there’s no good reason not to include them in the sensor suite unless you value profits over lives.
And I will point out that if the car in front of you isn’t paying attention and rams a stopped car in the middle of the road, you are fucked no matter what.
The day I heard that was the day I realized he’s a fucking idiot and I wanted nothing to do with his cars/tech.
Judging by how things have turned out…damn was that a good decision lmao
They pulled the RADAR from mine just before I took delivery, unbeknownst to me at the time. I received no sort of notification.
I tried watching it and it forces a horrible dubbing over it so I didn’t want to watch it. Apparently only way to chage it is to change my whole youtube account language
for the youtube website interface click on the gear wheel, and you can select the audiotrack you want
Yes, but not possible on mobile
I’m kinda confident that even RADAR + cameras was good enough, but they started shipping cars without it and even shutting off the RADAR in existing cars.
The main negative about LiDAR is the cost, but that’s quickly going down.
Why did they shut off radar?
They don’t want to install it in the newer cars, and they don’t want to make two software versions I guess. A backup would’ve been great though…
Thank you!
OMFG someone test to see if Teslas stop to eat free bird seed.
Meep meep!
So many Acme products we need to test, I saw one guy already successfully tested an Olmec statue.
Or a badly painted sign that says “Free charging”
Somebody with better animation skills than me make a cartoon where Wile E. Coyote is hunting cybertrucks using his old tricks and every single one of them works in his favor.
I’d buy that for a dollar!
All these years, I always thought all self driving cars used LiDAR or something to see in 3D/through fog. How was this allowed on the roads for so long?
tesla uses cameras only, i think waymo uses lidar.
Most non Tesla brands that have some sort of self-driving functionality use lidar and/or radar. I’ve got a BMW iX and as far as I know it uses cameras, radar, lidar, and ultrasonic sensors.
Money.
I remember reading that tesla only uses cameras for it’s self driving. My 2018 Honda uses radar for the adaptive cruise so the technology exists, musk is just an idiot.
Does it? My 2023 model throws a shit fit if it’s cold and I assume the camera covers are iced over.
It probably has cameras as well, for lane guidance etc.
My Mazda complains if the windscreen is dirty for the same reason.
Radar doesn’t detect stopped objects at high speed. It’d hit the wall too on radar alone.
This has to be solved by vision and or lidar.
they generally do
Suddenly, there are more Yellow Brick Road murals everywhere.
A building owner would not want cars crashing into their property though. Why would they get a mural to intentionally deceive a robot car?
The rain test was far more concerning because it’s much more realistic of a scenario. Both a normal person and the lidar would’ve seen the kid and stopped, but the cameras and image processing just isn’t good enough to make out a person in the rain. That’s bad. The test portrays it as a person in the middle of a straight road, but I don’t see why the same thing wouldn’t happen at a crosswalk or other place where pedestrians are often in the path of a vehicle. If an autonomous system cannot make out pedestrians in the rain reliably, that alone should be enough to prevent these vehicles from being legal.
Who owns the White House right now?
The question there would be does Austin have crosswalks that don’t have red lights. Many places put a light at every cross walk, but not all. Most beaches don’t have them at every crosswalk, they just have laws that if someone is in or entering the crosswalk you have to stop for the pedestrians. (They would all be at risk from what you are saying).
Yes, there are mid-block crosswalks in some of the walkable parts of Austin. There are also roundabouts with yield signs and crosswalks and no lights.
That will cause huge issues possibly. Do you live near there? We need to get this information to the public in those areas. Even if it is raining. Do not cross without checking over and over. We need to ban them from being there, but we need to protect the people first. 1 life may overturn the law, but 1 life shouldn’t be lost. It’s better we figure out an alternative
Not every pedestrian follows the rules of the lights though. And not every pedestrian makes it across the road in time before the light changes colors from red to green.
I didn’t say anything about whether it was adequate. The fact is it is going live. Trying to find weak spots and dangerous areas and point them out to people is all we can do at this stage.
I don’t know the answer to your question, but I’ll add that I’ve seen major cities that have overhead yellow flashing light boxes that mean “you must stop if there is a pedestrian crossing the road”
That should at least slow them down, but yeah it could be a real threat there as well.
Meep meep.
This is like the crash on a San Francisco bridge that happened because of a Tesla that went into a tunnel and it wasn’t sure what to do since it went from bright daylight to darkness. In this case the Tesla just suddenly merged lanes and then immediately stopped and caused a multi car pile up.
You’d think they have cameras with higher dynamic range and faster auto exposure in their cars by now. Nope, still penny pinching.
If only elon hadn’t insisted on not using lidar or anything other than just visible light cameras
Yeah, pulling radar from the cars was the beginning of the end. Early teslas had radar, and that was what led to all of the “car sees something three vehicles ahead and brakes to avoid a pileup that hasn’t even started yet” type of collision avoidance videos. First, pulling radar was a cost cutting thing. Then Elon demanded that they pull out the lidar too, and that’s when their crash numbers skyrocketed.
They never had lidar, as far as I know.
To any artists in Austin,TX: you have your work cut out for you. Godspeed.
Mark Rober is about to be listed as FBI public enemy #1 :(
EPA is going to investigate him for criminal fraud on Monday, I reckon.
Didn’t they dismantle them on Thursday?
