In Slovenia, a Tesla owner recently tested the company's supervised autonomous driving software, known as Tesla FSD, on the challenging Mangart pass, or Mangartsko sedlo. This mountain road is renowned for its steep incline and narrow lanes, making it a difficult route for drivers. According to a report, the test was recorded in a video shared on the owner's X account on Monday, September 14, 2026. The footage shows the Tesla navigating a complex maneuver on a road where, according to local traffic rules, ascending vehicles typically have priority in mountainous areas, unless there are exceptional circumstances. The video captures the Tesla moving at a speed of 30 km/h when it encounters a blind corner. The software detects a vehicle approaching from the opposite direction, and since there isn't enough space for either to pass, the Tesla executes a reverse and then a forward maneuver on the shoulder of the road. The car nearly brushes against the last concrete markers before the edge of the precipice. The passenger's reaction in the video suggests the situation was stressful, but the FSD completed the maneuver without any difficulty. After the Tesla and a motorcycle pass, a second motorcycle arrives, and the Tesla halts briefly, making slight steering adjustments to create enough space for the other rider. This ability to make precise adjustments is attributed to the software's detailed knowledge of the car's dimensions. In a prior test conducted by the French tech publication Numerama in Paris, the FSD's precision in maneuvering was highlighted, showcasing its capability to handle tight spaces with millimeter-level accuracy. The video provides a real-world glimpse into how Tesla's FSD software manages complex driving scenarios. It demonstrates the system's ability to assess its surroundings, make quick decisions, and execute maneuvers that would be challenging even for experienced human drivers. While the software is still under supervision and not fully autonomous, this test highlights its progress in handling intricate road conditions.
