Tesla has steadily pushed its Full Self-Driving (Supervised) platform beyond simple navigation, turning the underlying neural networks into an active guardian angel. While this previously meant stepping in with automatic emergency braking, the latest FSD builds can actually take over from the driver to steer the vehicle out of harm’s way. Now, we have our first real look at this new safety feature stepping in unprompted.
A video shared on Reddit by /u/casual-captain in the r/TeslaFSD community captures a rare instance of FSD automatically taking over steering while the driver was in full manual control.
The driver explained that they realized they forgot their wallet and were slowing down to make a U-turn: “I think what happened is that since FSD had already been active and I turned it off to start slowing down and merging over, at almost the exact same time the other car tapped its brakes, so the system immediately stepped in.”
Breaking Down the Clip
If you pay attention to the telemetry at the bottom of the Dashcam clip, you can see the sequence play out in real time:
From 0:00 to 0:12, the vehicle cruises under FSD’s control at around 43 mph.
At the 0:13 mark, the driver signals left and applies manual steering input, disengaging FSD and causing the blue “Self-Driving” status indicator to disappear.
Less than a second later, at the 0:14 mark, FSD is automatically re-engaged and the “Self-Driving” pops back up as an SUV passes on the left.
By 0:17, the driver applies deliberate counter-steering force to cancel the intervention (it’s amusing how we’re now having to use that word for FSD taking over from the driver and not the other way around) and safely completes the lane change.
While a passing vehicle on the left briefly taps its brakes, the gap wasn’t necessarily tight enough to present an immediate crash threat. Instead, we’re likely seeing Automatic Collision Evasion react to what it saw as an accidental FSD disengagement. According to Tesla, the feature will actively re-engage FSD if it concludes that the software was unintentionally disabled in running traffic.
How Automatic Collision Evasion Works
We first learned about this new feature when Tesla added Automatic Collision Evasion to the owner's manual. The feature officially arrived in software update 2026.27.6 earlier this month, which also brought FSD v14.3.9 and v14.2 Lite for older HW3 vehicles.
Automatic Collision Evasion comes into play in two scenarios. It can either trigger when the vehicle detects an imminent frontal collision on a controlled-access highway at speeds under 85 mph, and it determines that linear emergency braking alone won’t prevent an impact. If the path is clear, the system automatically engages FSD to steer around the hazard — swerving into an open lane or onto the shoulder.
Alternatively, the feature can kick in if the cabin camera detects severe driver inattentiveness or the vehicle suspects FSD was unintentionally disengaged, immediately re-engaging Self-Driving to stabilize the vehicle and keep it traveling safely down the lane.
Automatic Collision Evasion is exclusive to HW4 models and requires an active FSD purchase/subscription with both Automatic Emergency Braking and FSD (Supervised) enabled. Unlike standard AEB, which only applies linear braking, Automatic Collision Evasion actively maneuvers around obstacles — swerving onto shoulders or changing lanes at 22.5-85 mph if braking alone can’t prevent an impact.
During an active evasive maneuver, the accelerator pedal is muted and manual braking slows the car without canceling the evasive path. To cancel the action, drivers must apply firm, deliberate steering force to take manual control.
Automatic Collision Evasion doesn’t just prove how far the neural networks powering FSD have come but also shows how much confidence Tesla has in its tech, trusting it to function not just as driver-assist but also as an active safety feature.
