Tesla Cybertruck Owner Tests FSD by Recreating Mark Rober’s Fake Wall Stunt

Kyle Paul was inspired by Mark Rober’s viral video, where a self-driving Tesla famously plowed into a fake wall, to recreate the stunt. Unlike the former NASA engineer, he decides to perform the test using both a Model Y with Hardware 3 (HW3) as well as a Hardware 4 (HW4) Cybertruck.

In the first test, Kyle uses a 2022 Tesla Model Y with Hardware 3 (HW3) running Full Self-Driving (FSD) version 12.5.4.2. The fake wall—a flat, lightweight panel painted to blend with the road—is propped up on a quiet stretch, with a U-Haul truck parked behind it for safety (and maybe radar detection). He does multiple passes, but each time, the car’s visualization screen barely registers the wall until it’s super close—within a few feet. The FSD slows slightly but doesn’t stop on its own. Kyle has to slam the brakes manually to avoid hitting it, which he does every run.

Next, he switches to a 2025 Cybertruck with Hardware 4 (HW4) and FSD version 13.2.8—newer tech all around. Same fake wall, same road, just a bit later in the day (light’s still bright, no big shadows). The Cybertruck rolls up in FSD mode, same slow approach. This time, the visualization screen lights up earlier—around 20–30 feet out, you see it tag the wall as an obstacle. The truck slows smoothly and stops fully, a good 5–10 feet before impact, every single try. No manual intervention needed. Kyle credits the HW4’s better cameras and FSD 13’s sharper AI at—maybe that extra front camera helped, though he doesn’t confirm specifics.
