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!

    I am a bit disappointed to not see the Tesla crash into a real wall. I feel a bit click baited here.

    Also, they prepared the polystyrene wall to break this cartoonishly, but still played on being surprised.

      The purpose of the video is to test a hypothesis, not to total a car.

      Mark Rober is a youtuber sure, and some of the stuff he does is to feed the algorithm. But he’s also an engineer, and that involves experimentation and a good dose of science.

      Engineers won’t set up tests that intentionally destroy their expensive test equipment if they can conduct an equivalent test non-destructively.

    I saw the video pop up in my Youtube recommended, but didn’t bother watching because I just assumed that any cars tested would be using LIDAR and thus would ignore the fake road just fine. I had no idea Tesla a) was still using basic cameras for this and b) actually had sophisticated enough “self driving” capabilities that this could be tested on them safely.

      They are not still using cameras but removed LIDAR and radar from their cars during the chip shortage 2020/21. The story they were telling was “humans don’t have LIDAR but can drive cars as well, so the cars also only need ‘eyes’ like humans”.

        Small correction here: they never had LIDAR. Cars with LIDAR have big racks on top with a spinny thing measuring the surroundings. Teslas had radar but removed during the chip shortage (and disabled it on existing cars) and acted like it was an improvement. The radar was used for distance keeping on cars and could actually detect the car in front of the car by bouncing signals off the ground, it was really slick.

        That statement of him is not entirely wrong. But we humans have a very powerful bio computer that is perfectly tuned to process those visual inputs in realtime. Until a comparable performance is possible, removing LIDAR is very stupid.

          Besides that, in the fog and rain tests a human likely would have killed a kid anyway, and why settle for human limitations when you could be safer?

          We absolutely should also have lidar or analogous tech as part of a solution here, even if cameras did manage to get to human level safety.

          Yup, cameras and humans share various exploits. Self-driving is going to work better than humans once every car has it and communicates with each other, allowing for minimal gaps even at high speeds, once roads are all very standardized and in a database, and-

              It’s not a binary decision between all cars and no cars. If trains and public transit have enough capacity and convenience to make most trips feasible by them, car infrastructure will no longer have to be added (in fact can be converted into bus and bike lanes) while shortening trip duration (less cars = less jams) and improving safety.

              Also, you barely have luggage for most trips. 99% of my trips are made with luggage I can carry to the nearest stop and board the bus with.

                Yeah it’s not a binary decision, but trains are almost never the answer for a lot of people. If I’m going less than a couple hours, then I’m driving that distance. If I’m going much further than that, I’m flying. If I need to move a ton of stuff, I’m either taking my car or renting a uhaul. If I’m taking a lot of people, I’m taking my car. Trains never enter the picture unless I’m looking for variety in my mode of transport.

                And trains do not shorten the trip duratiion, not without absolutely kneecapping the roads. And over long distances, they’re absolutely slow compared to planes. In the short distance, they’re slow compared to cars.

                  So you’ll keep using it. And enjoy narrow but way less jammed streets. Maybe you’ll be incentivized/required to join the self-driving network, but in decades, not years, after positioning markers have been added to every road in the last repaving, while infrastructure funds have been directed towards making the city traversible for non-drivers.

      They tested a LiDAR rigged car, and it stopped just like you predicted. As of 2021, Tesla uses only cameras for FSD, and not even radar (which my stupid fine Toyota truck has).

      They tested the idea safely by building the wall out of styrofoam, or at least that’s what it looks like when it blows apart :)

        Why do you think lidar is not mature? It is radar, except it uses light and can get much more resolution than an RF radar. Or was that a joke… That was probably a joke… if it was then nm.

          That comment just missed the word ‘even’ - as in they don’t even have radar, and that’s on regular non-self-driving cars, and lidar would be a step above that.

            As far as I’ve seen, any system would be additive. If it has lidar, it would also have cameras and radar. So that you get the best of all the technologies (e.g cameras are the only only of the three that can follow lane markings)

        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…

        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.

          I think that’s largely because he wants to make his channel as kid-friendly as possible. If you watch some of his real early videos, he has a much calmer, more lecture-like demeanor without all the goofy edits and other modern YouTube tropes.

          His other big business venture is a subscription box for kids, which I think it aimed for around 8-13 year olds, so I imagine he’s adopted his current personality to try to appeal to that audience.

          It’s very modern, cheesy & spoon-feedy. Lots of staging. Overly friendly. Like it is filmed with the approval and oversight of HR.

          I know what you mean. He does some amazing things, but I tend to stick to the highlights rather than sit through whole videos. This one, the elephant toothpaste vid, and others like it can be watched as a 15 second clip if you just want to see the hook.

          It clearly works for his target audience, so I can respect sticking to the formula.
