Tesla's FSD Brakes Mid-Intersection, Averting a Potential T-Bone Crash

Tesla’s official X account shared a dashcam clip on Tuesday showing its Full Self-Driving (Supervised) system aborting a crossing midway through an intersection to dodge what could have been a serious side-impact collision. The footage came from an owner posting as TheNewGrid, who recounted the sequence at a stop sign: he assumed an approaching vehicle would halt, his car began to move, then stopped abruptly as the other driver blew through the sign.

What makes the clip stand out is the timing of the correction. FSD had already committed to the intersection when the other car ignored the stop sign. Rather than continuing forward, the software slammed on the brakes mid-crossing and waited for the vehicle to pass in front. The owner noted that he had made the same initial assumption as the system — that the other driver would stop — and admitted he would not have reacted quickly enough on his own. Tesla AI chief Ashok Elluswamy has previously described this kind of behavior as reacting to others cutting into your path at “super-human” speed.

The post is the latest in a string of safety-focused clips Tesla has pushed to its sizable X following in recent days. Over the weekend, the company amplified a video from Selling Sunset’s Jason Oppenheim, who traded his Bentley for a Model Y and said he was buying Teslas with FSD for ten of his employees. On Monday, a Cybertruck owner shared footage of FSD shifting across three lanes from a red light to clear a path for an approaching ambulance.

This particular save arrives shortly after Tesla began rolling out Automatic Collision Evasion alongside FSD v14.3.9, a function that can engage FSD on the driver’s behalf when a frontal impact seems imminent or when the driver looks distracted. Elluswamy indicated in September that v15 — the build tied to around-the-clock Robotaxi operation — would deliver earlier hazard prediction and quicker reactions.

Beyond social media, the safety narrative carries regulatory weight. Tesla states that FSD Supervised was 4.1 times less likely to crash than manual driving across 100 million kilometers logged on European roads, figures it has presented to officials. Eight EU countries have now cleared FSD Supervised, with Croatia the most recent, though the bloc-wide vote initially slated for October 6 has slipped to December at the earliest.

It’s worth keeping in mind that FSD Supervised remains a Level 2 system, meaning the driver stays responsible at all times. Even frequent users report occasional reasons to take over. Clips like this one highlight the flip side: instances where the software caught a mistake a human was about to make.
