Watch Tesla FSD's New Automatic Collision Evasion Feature in Action [VIDEO]

Tesla continues to advance Full Self-Driving (Supervised) from navigation toward active safety. Beyond automatic emergency braking, recent FSD builds can momentarily assume steering to guide the vehicle out of danger. A new clip provides an early look at the system intervening on its own during a manual lane change.

A video posted to Reddit by /u/casual-captain in r/TeslaFSD shows FSD re-engaging and taking the wheel while the driver was in full manual control.

The driver explained: “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

Watching the telemetry at the bottom of the Dashcam clip shows the sequence 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 and completes the lane change.

A passing vehicle on the left briefly taps its brakes. According to Tesla, the feature will actively re-engage FSD if it concludes that the software was unintentionally disabled in running traffic, which matches the intervention seen in the clip.

How Automatic Collision Evasion Works

The feature was added to the owner’s manual. It officially arrived in software update 2026.27.6 and coincided with FSD v14.3.9 and v14.2 Lite for older HW3 vehicles.

Automatic Collision Evasion activates in two situations. It can trigger when the vehicle detects an imminent frontal collision on a controlled-access highway at speeds under 85 mph and determines that linear emergency braking alone will not prevent an impact. If a path is clear, the system engages FSD to steer around the hazard, swerving into an open lane or onto the shoulder.

Alternatively, it can engage if the cabin camera detects severe driver inattentiveness or the vehicle suspects FSD was unintentionally disengaged, immediately re-enabling Self-Driving to stabilize the vehicle and keep it safely traveling down the lane.

Automatic Collision Evasion is exclusive to HW4 models and requires an active FSD purchase or subscription with both Automatic Emergency Braking and FSD (Supervised) enabled. Unlike standard AEB, which only applies linear braking, it actively maneuvers around obstacles—swerving onto shoulders or changing lanes at 22.5-85 mph if braking alone cannot 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, drivers must apply firm, deliberate steering force to take manual control.
