Watch Tesla FSD Avoid Obstacles in Just 0.13 Seconds [VIDEO]

Tesla's Full Self-Driving (Supervised) is developing a track record for reacting to real-world hazards faster than a human. To quantify how quickly it handles a sudden obstacle, longtime Tesla enthusiasts AI DRIVR and David Moss recently put the system’s safety logic to the test in a new YouTube video.

Moss previously drew attention for reaching almost 13,000 miles of intervention-free FSD driving and completing the first fully autonomous, coast-to-coast FSD drive across Canada without human input. For this experiment, the pair used a life-size blow-up doll named Dan O as a crash test dummy, throwing it directly into the path of a Model Y operating on FSD (Supervised) at various speeds and tightly timed intervals to evaluate the reaction window.

Blinking Faster Than Humanly Possible

AI DRIVR described FSD v14.3 as having an “inhuman reaction time.” To demonstrate this, they mounted a camera on the roof to capture the precise moment Dan O moved off the curb and into the Model Y’s path.

At 32 mph, the FSD visualizer identified the obstacle and began an aggressive evasive maneuver in just four frames. At 30 frames per second, that equates to a reaction time of 0.13 seconds — faster than most people can blink. Even when Moss dropped the dummy straight onto the asphalt at 40 mph to mimic a pedestrian tripping forward, the vehicle executed a clean swerve to avoid it.

Elon Musk has said the current v14 stack is already far safer than the average driver. Tesla plans to launch FSD version 15 toward the end of this year or early next year, which is expected to introduce a massive 10x parameter upgrade.

The Blind Spot Dilemma

The testing also surfaced a situation where the car stopped to avoid the dummy and then shifted into reverse. Because older (pre-Juniper refresh) Model Ys don’t have a front bumper camera, backing up placed the fallen dummy directly in a blind spot. The center screen displayed "Object in path detected," but without a low-level front camera, FSD appeared to lose track of the dummy and attempted to pull forward again.

Tesla began rolling out FSD v14.3 earlier this spring with software update 2026.2.9.6, followed by rapid point releases. This week, software update 2026.14.6.10 started reaching vehicles, adding new FSD streak celebrations and Actually Smart Summon for the Cybertruck.
