Tesla Autopilot drives into Wile E Coyote fake road wall in camera vs lidar test
Tesla Autopilot drove into Wile E. Coyote-style fake road wall in the middle of the road in a camera versus lidar test.
While most companies developing self-driving technologies have been using a mix of sensors (cameras, radar, lidar, and ultrasonic), Tesla insists on only using cameras.
The automaker removed radars from its vehicle lineup and even deactivated radars already installed in existing vehicles.
The strategy has yet to pay off as Tesla’s systems are still stuck at level 2 driver assist systems.
CEO Elon Musk claims that Tesla’s advantage is that once it solves autonomy, it will be able to scale faster than competitors because its vision plus neural net system is designed to work like a human driver and, therefore, will be able to adapt to any road.
Critics have pushed back against those claims, especially since Musk mentioned Tesla achieving “level 5 autonomy”, which means “in any conditions,” and cameras have limitations on that front that are fixed by lidar sensors.
A new video by engineering Youtuber Mark Rober has provided a very interesting demonstration of that very problem:
In the video, Rober puts a Tesla Model Y on Autopilot against a vehicle using a lidar system in a series of tests in different conditions.
The Tesla on Autopilot managed to stop for a kid mannequin in the middle of the road when statics, moving, and blinded by lights, but it couldn’t stop in fog or heavy rain:
It’s not surprising that the lidar, a laser-based system, is capable of detecting better in heavy fog than a camera system.
The heavy rain was a bit more surprising, but to be fair, the level of rain was quite spectacular.
The last scenario of a Wile E. Coyote-style wall with a fake road painted on it was obviously not realistic, but it serves to illustrate the issue with cameras versus radar or lidar sensors: they rely on the perception of potential obstacles rather than hard data about potential obstacles.
In simple words, the lidar sensors didn’t care what was painted on the wall, they only cared that it was a wall, while cameras can be tricked.
Electrek’s Take
I think it’s clear that no Tesla vehicle currently available will be capable of level 5 autonomy as Elon claimed.
Level 4 is also questionable.
I think you can accomplish a lot with cameras, but I think it’s undeniable that adding radars and lidars can make systems safer.
In DMs with us during Tesla’s transition to vision only, Elon even admitted that “very high-resolution radars would be better than pure vision”, but he claimed that “such a radar does not exist”:
“A very high-resolution radar would be better than pure vision, but such a radar does not exist.”
When we pointed one out to him, he didn’t respond. Also, while they use light rather than radio waves, lidars are basically high-resolution radars, but the problem is that Musk has taken such a strong stance against them for so long that now that they have improved immensely and reduced in prices, he still can’t admit that he was wrong and use them.

Plus, with the Beatbot app, you can easily track cleaning progress and view detailed cleaning maps in real time.
Say goodbye to juggling multiple pool-cleaning devices—the AquaSense 2 Ultra delivers unmatched convenience with its unique 5-in-1 cleaning system. This robotic marvel tackles everything: water surface, waterline, floor, walls, and even a ClearWater Clarification System. Powered by an industry-first 11-motor submarine propulsion system, it transitions effortlessly between floating and diving, guaranteeing complete and comprehensive coverage every time.
Never worry about overlooked debris again. The Ultra’s Advanced AI Cruise Debris Detection system scans your pool after the initial clean, intelligently identifying and removing any stragglers like leaves. Its AI-driven camera and sensors continually learn and improve, recognizing different leaf types such as oak, maple, palm, and more. The result is an impressively thorough clean that traditional robots simply can’t match.
And when it comes to effortless pool management, the AquaSense 2 Ultra truly shines. With dual side brushes designed to sweep debris directly into the cleaner’s path, even pool corners and edges get pristine cleaning. Plus, the Beatbot app’s advanced navigation control lets you manually steer the AquaSense 2 Ultra across the water’s surface, making spot cleaning both precise and fun.
Finally, retrieval is easier than ever with Beatbot’s exclusive Smart Water Surface Parking technology. When cleaning finishes, or battery life falls below 15%, the AquaSense 2 Ultra autonomously returns to the pool edge, floats to the surface, and automatically releases water to make retrieval lighter and effortless. If it drifts, simply use the app’s one-touch retrieval button to bring it back to you.
The Beatbot AquaSense 2 Ultra is normally priced at $3,450 and is 15% off until March 31.

Toyota the EV battery supplier? Honda will use them to power up its 400,000 hybrids in the US
Toyota is now a battery supplier? That’s the plan. Honda will use Toyota’s batteries to power up its around 400,000 hybrids sold in the US.
Toyota will supply batteries for Honda hybrids in the US
Toyota’s $14 billion battery plant in North Carolina is ready for business. The facility will begin shipping out batteries next month, and it looks like Toyota already has its first customer.
According to a new Nikkei report, starting in fiscal 2025, Toyota will supply batteries for the roughly 400,000 Honda hybrids sold in the US.
Honda currently uses batteries from China and Japan for vehicles sold in the US, but the company is (like most) preparing for changes under Trump.
Honda’s electrified vehicles, including EVs and hybrids, accounted for over a quarter of US sales last year. The company sold over 308,500 hybrids and 40,400 electric vehicles in the US in 2024. The batteries will likely be used in the CR-V and other Honda hybrid vehicles.
Earlier this month, an extra 10% tariff on imports from China took effect. And that’s on top of the 10% imposed in February.
With more expected, including a 25% increase in vehicles imported from Japan, automakers are tightening up their supply chains.
A 25% tariff on Japanese vehicles, up from 2.5% currently, is estimated to cost the six major Japanese automakers about $20 billion in the US.
Tariffs on imports from Mexico and Canada could cost Honda roughly $4.7 billion alone. Teaming up with Toyota to use its batteries for its hybrids is part of Japan’s broader global plans to ween off dependence on China and others for batteries and other emerging tech.
The new US plant, Toyota Battery Manufacturing North Carolina (TBMC), is over seven million square feet, or about the size of 121 football fields.
As Toyota’s first in-house battery factory outside of Japan, the plant could be a game changer as Trump’s tariffs take effect. Securing Honda as a buyer will already help Toyota cut costs as it ramps up output.
Toyota plans to ramp up electrified vehicle (EV, PHEV, and hybrid) sales in North America from around 40% last year to 80% by 2030.
Electrek’s Take
Trump’s tariffs are already causing havoc, with nearly every automaker warning that they put the US further behind. Overseas automakers are not the only ones feeling the heat, either.
The “Big Three,” GM, Ford, and Jeep maker Stellantis all build vehicles in Canada and Mexico. GM cut output at its plant in Mexico in January, where the electric Chevy Equinox, Blazer, and Honda Prologue are made. Stellantis halted operations at its Brampton Assembly Plant in Canada last month, where it was expected to launch the Jeep Compass EV production. What’s next?
For Toyota, it looks like its $14 billion bet to build batteries in the US is already paying off. Now, we just need it to introduce more EVs.
After unveiling three new electric SUVs in Europe last week, including the updated bZ4X, Toyota hinted more is on the way for the US. Check back soon for updates.
What do you think? Do you want to see more Toyota EVs in the US, like the new C-HR+? Let us know your thoughts in the comments.
