Tesla’s Wild ‘Fake Road’ Test Reveals Why Only the Cybertruck Can Outsmart Tricky Obstacles in 2025
Inside a stunning experiment that split Tesla’s fleet: Discover the hardware leap putting true self-driving within reach for 2025.
- 21x: HW3’s performance leap over its predecessor in 2019.
- 144 vs. 500 TOPS: HW3 delivers 144 trillion ops/sec, HW4 up to 500 trillion.
- $2,000: Approximate cost per Tesla of the full HW4 self-driving hardware suite in 2025.
- 13 Million: Estimated global autonomous EV sales by 2030 (IEA).
Imagine barreling down a desert highway in your new Tesla. Suddenly, the ‘road’ ahead isn’t real—it’s a mural pasted on a wall. Would your car recognize the danger, or plow straight ahead? In a jaw-dropping 2025 test, Tesla’s Model Y and Cybertruck faced off against this ‘fake wall.’ The results rocked the auto world—and revealed just how far, or not, Tesla’s self-driving tech has come.
Here’s what happened. Independent YouTuber Kyle Paul set up a simulated road, painting a continuation of the lane onto a plastic blockade. When the 2022 Model Y (running ‘old’ Hardware 3) faced the test, its sensors were fooled—the car would’ve crashed if not for human intervention. But when the Cybertruck, packing Tesla’s latest Hardware 4 (HW4), took the challenge, it stopped itself cold, instantly recognizing the hazard.
What Makes HW4 a Game-Changer for Tesla’s Self-Driving?
At the core of this leap is Tesla’s relentless push into custom semiconductors. The HW4 chip, introduced in 2023, dwarfs its 2019 predecessor (HW3) in brute computational power. While HW3 processes 144 trillion operations per second (TOPS), HW4 pushes that number to a staggering 300–500 TOPS, all on an efficient 5nm process.
The HW4 suite packs twelve high-res cameras, reintroduced radar, and lightning-fast image processors—letting the car “see” and react to complicated scenes, even in heavy rain or snow. Behind the scenes, Tesla’s AI models, continually fed on billions of miles of driving data, do the rest.
It’s a feat of electronics and artificial intelligence familiar to industry-watchers tracking the Nvidia and Samsung arms race.
Q: Why Did the Model Y Fail the ‘Fake Wall’—But the Cybertruck Didn’t?
The key difference? HW3 isn’t equipped to distinguish ultra-realistic 2D images from actual roadway. Its lower processing limits and fewer, older cameras can be blinded by clever deceptions—a major risk at highway speeds.
HW4, by contrast, processes hundreds of frames per second from more perspectives, fusing visual, radar, and even ultrasonic data. Even a hyper-realistic photo becomes, to HW4’s logic, an obvious obstacle. The experiment highlights why self-driving upgrades are more than just software—they’re about silicon muscle, too.
How Did Tesla Reach HW4—and What’s Coming Next?
The journey started in 2014, when Tesla’s first autopilot chip (HW1) ran on Mobileye’s EyeQ3. After a fatal early accident, Tesla cut ties, hired Silicon Valley chip legends like Jim Keller, and ramped up to HW3 in 2019—a chip offering 21x faster vision analysis and system redundancy.
But with robo-taxis and true autonomy on the horizon, even that wasn’t enough. Musk’s team engineered HW4, raising integration, sensor count, and raw AI power. Tesla’s data centers now run thousands of Nvidia H100 GPUs, supplementing in-vehicle inference with massive cloud learning.
By 2025, Tesla is expected to unveil a next-gen chip, rumored as “AI5,” boasting up to 2,500 TOPS, with hardware partners at TSMC and Samsung ready to mass-produce the brains of future fleets.
Will Tesla’s Chip Power Outpace Global Rivals?
The ‘chip war’ for AI-driven cars is a multi-trillion-dollar contest, with Google (Waymo), Baidu, and other giants racing for dominance. Each aims to make end-to-end autonomous driving (no steering, no pedals) the new normal, freeing elderly or disabled riders while disrupting millions of taxi, delivery, and trucking jobs worldwide.
Tesla’s investment in AI hardware now tops $10 billion in just the past year. As governments race to update self-driving regulations by 2029, the next frontier isn’t just smarter software—it’s supercharged, safety-critical silicon.
South Korea and other nations are now strategizing to avoid being left behind, investing heavily in AI chip research to compete for tomorrow’s roads.
How Can You Tell If Your Tesla Has HW4? (And Should You Upgrade?)
If you drive a Cybertruck or a new Model S/X delivered after mid-2023, HW4 is standard. Earlier Model Ys and 3s still rely on HW3. Tesla hasn’t announced retrofit options, but don’t be surprised if demand surges as more owners see how much better HW4 handles edge-case scenarios like the ‘fake wall.’
