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 […]

    I really enjoyed this video, but one thing bugs me a bit. Why does he specifically call attention to Tesla as a brand and not Luminar? If he’s trying to be scientific about the technology, it should be “lidar vs imaging”. Or if he does want to call out brands, “Luminar vs Tesla”. Not that I’m defending Tesla, but this just seems weird to me when his videos are typically more educational.

      If Kleenex were the only ones doing facial tissue, then this could be, “toilet paper vs. Kleenex”, and you’d be wondering “why isn’t this Charmin vs Kleenex?” while Charmin happened to be the TP brand they chose because they had access to it.

      Tesla is the only one doing camera-only self driving, so there’s no point in delineating the two. Lidar you can expect from any other brand, so it’s a token choice in this instance, especially for an engineering entertainment video.

      In an interview post video release he mentions only using the Tesla as is the only one he’s aware of only using cameras. Luminar wasn’t named as a car brand or anything really as this was not intended as a promotion for them.

      He even said during the interview he loves his Tesla and will more than likely buy another. Which tbh was a bit disappointing. But I do think highlights most of the criticism here is largely unfounded and fanboy antics.

      I’m sure he knows Tesla gets the most engagement. And I also believe Tesla is the only company that doesn’t use lidar and Musk has been very vocal about lidar being unnecessary for self driving.

        If you mean like, self-driving then I don’t know. Subaru has lane-assist and adaptive cruise control that uses only cameras though. They use two cameras for binocular vision though so it might not fall for this, I don’t know. Would be a good test.

          I probably should have said “only cameras”. Subaru, like the rest, backs the cameras up with radar to avoid situations like in the video.

          Edit: welp, apparently not in the front

            I think I accidentally deleted my post so sorry if this is a duplicate.

            I can poke around in my wife’s outback to verify again, but as far as I’m aware, Subaru doesn’t have any forward radars. Having a set of properly calibrated stereo cameras works amazingly well though. Whatever Tesla is attempting, while still kinda impressive, isn’t nearly as polished with the number of phantom breaking events and stuff like this I see complained about online.

            Blind spot I believe is radar, and backward is a combination of sonar and radar if I’m not mistaken.

                Just because you seem to be quick to read these and I wanted to mention the vision limitation one after I understood it better.

                In my experience with the Outback, it should either work just fine, or if visibility is too bad for it to work reliably, it won’t let you engage it (or warn you and turn itself off it conditions deteriorate while engaged.)

                If the speed difference between the car and the object is over 32mph (at least for 2018 model year if I’m remembering the number in the manual correctly), I believe it will fail because it doesn’t have enough time to identify the object. It will do it’s damndest to stop, and should be able to scrub off a solid amount of speed, but there will still be some sort of impact just due to pretty clearly spelled out system limitations.

          My experience with two different brands is that ACC is unable to detect static objects. Its only strength is detecting moving vehicles in front of you. So even if you come to a stoplight with cars already waiting there, it will just continue going. Other systems must then engage emergency breaking if they detect something but at regular speeds that would be too late.

      Because there’s little reason to think different lidar systems would perform much differently on these tests and Tesla is the big name that uses exclusively imaging for self driving.

      Wouldn’t many humans drive into such a wall too?

      I read the article but not seen the video.

        It’s not about the wall. That’s just for shits and giggles (and clickbait). The real problem is that the Tesla also ran over a mannequin in rain and fog, while the Lexus with lidar did not.

        They show a still photo in the video, where the engineer comments on that. He highlights the wrinkles in the wall image, imperfections and shadows that a human can see. The way he told it, it was hard to miss to a human
