FSD Stuns Reviewers: Elon Musk’s System Outsmarts a Human Driver in Key Test

At a closed test facility, the teams behind Out of Spec Reviews and Dirty Tesla put Tesla’s Full Self-Driving system through a string of unusual trials. Their idea was simple: see how the software behaves when other cars act like impatient or aggressive drivers—cutting in sharply, drifting toward the lane, or making sudden, unpredictable moves nearby. Throughout the tests, the Model 3 running FSD not only dodged potential contact with confidence, but often reacted in ways that many everyday drivers might not manage.

In one sequence, the car automatically opened up its following distance after being passed, and later even chose to turn around entirely to avoid traveling alongside the “aggressor.” When the two vehicles approached each other head-on, FSD began slowing far earlier than expected. And when a car pulled out from the shoulder, the Tesla eased to a stop almost without any abrupt braking.

If the vehicle had no good option other than leaving the roadway, the system preferred to roll onto the grass rather than risk a collision. The testing showed that the software can read developing threats and pick the safer escape route—even in scenarios it likely wasn’t explicitly trained for.

These trials were run on FSD Supervised version 14.1.7. Despite the clear progress, the technology remains controversial: it is currently under investigation in the United States, and European regulators still don’t allow it on public roads.
