Tesla on FSD makes stressful cliffside reverse on Slovenia mountain road to let traffic passThe Cool DownJames NanzoThu, September 24, 2026 at 6:19 PM UTCAdd us on GooglePhoto Credit: iStockA video from Slovenia shows a Tesla using FSD Supervised while reversing beside a steep drop-off on a cramped mountain road so oncoming traffic could get through.The clip captures a difficult, low-speed maneuver that many drivers would likely find stressful even with full control of the wheel.Here's what to knowJan Skočaj originally shared the scene on X, showing a maneuver on Mangart Saddle Road in Slovenia, a route that rises to about 6,742 feet (2,055 meters).AdvertisementAdvertisementAs the Robotic (@robotic) Instagram account described in a post, the road is known for narrow sections and sharp exposure along the edge.The car moves backward toward the cliffside while a van and a motorcycle squeeze past it, and the driver's hands are off the wheel.Even so, the scene should not be read as fully self-driving in the everyday sense. The post noted that FSD Supervised remains a driver-assistance feature, so a human driver is still expected to watch the road closely and be ready to take control immediately.In fact, the carousel slide that shows the full view of the cabin reveals that the driver's hands are nearby to address any mistakes the system might make in the fraught situation.More backgroundThis is less a normal driving example than a stress test. Situations with almost no room to spare on a mountain road are exactly the kinds of moments that fuel arguments about what advanced driver-assistance systems can realistically handle.AdvertisementAdvertisementSoftware is increasingly part of what people consider when choosing an EV, alongside price, range, safety features, and charging convenience. Moments like this can help illustrate what different systems can and cannot do.For each positive example like this, there are drivers who remain hesitant or point to different experiences."Whoever was in the back seat of that Tesla must have seen the gates of heaven with their eyes closed," a user joked.What can be done?Features such as FSD Supervised require drivers to understand the system's limits and stay alert, keep their eyes on the road, and be ready to take over immediately, especially on narrow roads, in bad weather, or around unpredictable traffic.AdvertisementAdvertisementDriver-assistance features can vary widely across vehicles. User experience, software updates, camera visibility, and low-speed behavior can all shape how helpful an EV feels in daily driving.The footage was undoubtedly impressive, as was arguably the driver's willingness to trust the technology.A commenter reacted: "FSD on a cliff! You bolder than me."Where can I learn more?Tesla's FSD Supervised technology has generated a lot of different reactions beyond a single mountain-road clip.• In Europe, drivers have said Tesla's FSD speaks differently when road rules and signage change.• Experts testing Tesla said Full Self-Driving still raises serious questions before public rollout.AdvertisementAdvertisement• In France, regulators warned that Tesla's self-driving claims could mislead drivers about autonomy.Get TCD's free newsletters for easy tips, smart advice, and a chance to earn $5,000 toward home upgrades.
