Can a Tesla See Through Fog? The Truth About Camera-Only AI

Can You Trick a Self-Driving Tesla? The Truth About Camera-Only AI

What's up, I recently watched this wild video of Mark Rober in his Tesla, hands off the wheel, as autopilot takes him straight toward a fake road tunnel painted on a solid wall—just like in a Looney Tunes cartoon.

"Please stop. Please stop. Oh sh—"

Spoiler: It didn’t stop. Tesla’s autopilot, which relies only on cameras, saw the fake tunnel and thought, yep, looks real enough!

How easy is it to fool a self-driving car that doesn’t use LiDAR? Could bad weather, shadows, or optical illusions throw it off? If Tesla is putting all its faith in cameras, can it actually “see” the world accurately?

He put Tesla’s vision-only AI through the ultimate deception test.

The Problem with Camera-Only Self-Driving Cars

Most self-driving systems (like Waymo, Mercedes, and GM’s Cruise) use three types of sensors:

🚗 LiDAR (Light Detection and Ranging) – Shoots out laser pulses to create a real-time 3D map. It’s immune to bad lighting, fog, and visual illusions.

📡 Radar – Uses radio waves to detect objects, even through rain or fog.

📷 Cameras – Recognize road signs, lane markings, and objects—just like human eyes.

Tesla, however, ditched LiDAR and radar entirely. It relies only on cameras and AI-driven image recognition to understand the road.

That’s like saying, “I don’t need depth perception or night vision—I’ll just squint really hard and figure it out.”

So, let’s see if Tesla’s camera-based autopilot can handle real-world deception.

The Deception Tests: Fooling Tesla's AI

They designed four experiments to see how well Tesla’s vision-only autopilot handles fake obstacles, bad weather, and optical illusions.

1️⃣ The Fake Child Test (Does Tesla Brake in Time?)

They placed a life-sized mannequin child in the middle of the road. The Tesla was moving at 40 mph on autopilot. Would it stop in time?

✅ Outcome: Tesla braked—barely. It detected the child but hesitated before stopping.

🔎 Lesson: Tesla’s cameras can recognize objects, but they take longer to react. LiDAR, in comparison, stopped immediately in the test with a LiDAR-equipped car.

2️⃣ The Fog Test (Can Tesla "See" in Bad Weather?)

They created a dense fog bank using industrial fog machines to test whether Tesla’s cameras could navigate low visibility.

❌ Outcome: Tesla completely failed. It drove straight through the fog without slowing down.

🔎 Lesson: Unlike LiDAR (which doesn’t rely on light), cameras are useless in fog, rain, or snow. Tesla’s system struggled to “see” the road at all.

3️⃣ The Optical Illusion Test (Can Tesla Detect Fake Roads?)

They painted a fake 3D road tunnel on a solid wall—just like a Wile E. Coyote cartoon.

❌ Outcome: Tesla crashed straight into the wall. It thought the tunnel was real and didn’t even tap the brakes.

🔎 Lesson: Tesla’s cameras rely on image recognition, not depth perception. A LiDAR-equipped car would have instantly recognized the wall as a solid object.

4️⃣ The Shadow Trick (Does Tesla Mistake Shadows for Real Obstacles?)

They placed a large shadow on the road to see if Tesla would mistake it for an actual object.

✅ Outcome: Tesla panicked and braked suddenly, thinking the shadow was a real obstacle.

🔎 Lesson: Unlike LiDAR (which detects actual objects), Tesla’s cameras can be fooled by shadows—a major flaw in image-based AI.

Is Tesla's Camera-Only AI Reliable?

‍Fake Child Test

• Result: ✅ Stopped (slow reaction)
• ‍LiDAR Comparison: ✅ Stopped instantly

Fog Test

• Result: ❌ Failed
• ‍LiDAR Comparison : ✅ No issue

Fake Tunnel Test

• Result: ❌ Crashed into wall
• LiDAR Comparison: ✅ Stopped immediately

‍Shadow Test

• Result: ❌ Mistook shadow for an object
• LiDAR Comparison: ✅ Ignored the shadow

Tesla’s vision-based system works fine in perfect conditions. But in fog, rain, or with visual illusions, it fails—badly.

LiDAR wins every time. It measures depth and shape, while Tesla’s cameras can only guess based on 2D images.

So, Can You Trick a Self-Driving Tesla?

Yes. Easily.

✅ If the car uses LiDAR, it’s much harder to fool. It measures depth, not images.

❌ If the car only relies on cameras (like Tesla), it can be tricked by fog, shadows, rain, and fake obstacles.

Tesla’s vision-based AI is impressive, but it’s not foolproof. If Tesla ever added LiDAR, it could be game over for the competition. But for now? Maybe don’t trust it to drive itself in extreme conditions.
