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!
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.
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
Anyone that works in automation will tell you you can’t use software to overcome deficiencies of your sensors. They were too cheap to include a reliable Lidar, and now can’t have a car that knows where obstacles are.
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.
It got fucking wile e coyoted
Still think LIDAR is inferior to computer vision, Elon?
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 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 :)
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”.
And let me just add, Musk ordered the LIDAR removed against the engineers better judgement.
I’ll add that every other self driving car company has a pretty good safety record, specifically because they do use LIDAR and RADAR so they can see better than humans.
Humans cannot, in fact, drive cars well. Humans kill tens of thousands of other humans with cars every year in the US alone.
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-
Wait, that’s trains
Fucking build more electrified high-speed rail and forget tech bros’ shitty promises
Trains don’t go from my driveway to my destination exactly when I feel like going there, while carrying all my luggage.
I get that it’s fun to be smug on the Internet, but private vehicles aren’t going away any time soon.
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.
I have a van load of tools to transport most of the trips I make.
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.
TIL Mark Rober is a domestic terrorist
