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!
Things that happen when you rely exclusively on optical sensors, i.e. cameras. But that’s just cheaper, more money for Nazi Elon.
Turns out having radar is rather important…
It’s dirt cheap, too. If this was a cost-cutting measure, it was a thoroughly idiotic one. Which feels like the mark… of a certain someone I can think of
This would be hilarious if it weren’t for shitty cars causing deaths.
That said, I always wondered why we don’t find a system like RFID that could penetrate concrete and asphalt, and plant passive receivers in roads? We re-pave roads so damn often in this country (the U.S.) it seems like we could’ve knocked it out in the past couple of decades, minus our most rural areas.
I know RFID itself isn’t strong enough, but I imagine that would’ve been an easier problem than figuring our complete self driving. Not to mention making GPS a secondary system for U.S. road travel in most cases.
Maybe it’s just a dumb shower thought?
I have another idea: echolocation and laser measurement.
Echolocation is specifically audio based.
Lidar is a similar technique, but much more accurate and precise.
Project a grid of laser beam, read when the laser bounces back, you know the distance to that part of the grid.I don’t know the value of echolocation in this case, as I’m generally ignorant here, but it’s straight wild to me that they went purely on visuals.
Tesla used to also have radar (and maybe lidar?) but they removed it as a cost cutting measure. If you ever see older videos of a Tesla slowing down or stopping due to a potential collision a few cars ahead, that’s from before they switched to only relying on cameras. The collision avoidance was significantly better back then.
Insurance fraud is going to bankrupt Tesla robotaxis faster than an incompetent CEO ever could.
There will be too many ways to defeat the cameras and not having LiDAR unlike the rest of the industry may prove to be found to be a failure of duty of care.
I remember Elon foolishly saying his cars don’t need radar or lidar. Even software-disabling radar in cars that already had the hardware.
Not even just his cars, he thinks the MILITARY, doesn’t need radar and can just use cameras to spot and track stealth fighters.
He’s a fucking lunatic.
I mean his right, his cars don’t need radar or lidar. They just drive into things.
Yeah but the radar/lidar may allow them to drive into things quicker.
Make Elon test ride the first Tesla robotaxi and there’s a chance the funniest thing of all time will happen.
Some cartoon shit
My vacuum would pass that test… why is a Tesla worse at this?
This
In short because Elon (wrongly) believes you only need cameras, he made the claim people also drive with just 2 eyes.
The thing is, we recognize a truck with stickers of a stopsign, while AI vision gets confused.
Waymo (Googles self driving side hussle) was build on lidar and other sensors and has been using robot taxis for many years now in geofenced specific areas.
The thing is, we recognize a truck with stickers of a stopsign, while AI vision gets confused.
Lmao would it be illegal to put a stop sign on the back of your car?
I was thinking the same thing. What would happen if you popped one out of the back of your car while driving in front of a self driving car on the freeway?
This is why it’s fucking stupid Tesla removed Lidar sensors and relies on cameras only.
But also who would want a tesla, fuck em
They never had lidarr. They used to have radar and uss but they decided “vision” was good enough. This conveniently occurred when they had supply chain issues during covid.
I was horrified when I learned that the autopilot relies entirely on cameras. Nope, nope, nope.
Leon said other sensors were unnecessary because human driving is all done through the sense of sight…proving that he has no idea how humans work either (despite purportedly being a human).
They also removed radar, which is what allowed them to make all of those “it saw something three vehicles ahead and braked to avoid a pileup that hadn’t even started yet” videos. Removing radar was the single most impactful change Tesla made in regards to FSD, and it’s all because Musk basically decided “people drive fine with just their eyes, so cars should too.”
Meep meep!
Apparently they keep getting tickets in China because they didn’t bother to adjust the settings to accommodate Chinese roads and traffic laws. Result is Tesla is getting utterly crushed by BYD in their one major market that doesn’t care about Elon’s antics.
Huh, now I’m mildly interested in the differences in traffic laws in China vs US vs Europe that lead to Teslas getting more tickets in China than elsewhere.
I found this article. My takeaways were:
- No driving in bus lanes during certain times of day.
- No using the shoulder as a turn lane.
- No using a bike lane as a turn lane.
Wow

This post brought to you by American car centrism
Not sure what “American car centrism” has to do with Chinese traffic regulations tbh
I think their regs, while seemingly very basic rules of the road, are based because I live in the US and we have bike lanes here that just whole ass turn into turn lanes with almost no warning. I wish we could get basic decency for everyone on the road, too.
I am very glad that Elon and Trump have overreached and now Tesla is suffering. I hope Starlink is the next domino to fall.
Yup plus the European Union is making their alternative to launch in a year or 2
Good.
I’m not rooting for America to fail, but I’m 100% rooting for Elon to fail.
New stuff to add to the car kit bag for the 21st century
- poster board to block usonic weapons
- black paint, white paint, roller, brush to paint tunnels on walls
- orange cones to pen in self driving cars
And a “Yikes!” sign 🤣
That’s some Wiley Coyote shit if I ever saw it.
There’s a very simple solution to this. BUILD MORE TRAINS!
