Tesla's FSD Supervised Update Activates Collision Avoidance During Manual Driving

Tesla announced a new FSD Supervised software update that can intervene during manual driving to avoid collisions, but the feature remains rolling out and has unresolved safety questions.

Tesla announced FSD Supervised v14.3.9 on September 4, 2026, which activates collision avoidance during manual driving when Automatic Emergency Braking is insufficient. The update also triggers if drivers are heavily distracted or have accidentally disengaged the system. It operates as a background safety feature during manual driving but has not yet been fully deployed. Tesla stated the feature is 'starting to roll out shortly' without confirming disable options or explaining how the system determines steering is safer than braking.

This update addresses specific collision scenarios in supervised driving but does not reduce vehicle costs or expand mobility access for most users. Historical v14 software has been linked to unexplained swerving and phantom braking incidents, raising concerns about its reliability. Tesla has not clarified whether drivers can disable the feature or how the system decides between steering and braking.

For now, this update moves safety for Tesla vehicle owners using manual driving in collision-prone situations. It does not advance abundance in the MANY MINDED sense—since it neither lowers costs nor increases access for broader populations. What matters next is whether Tesla resolves the safety questions around decision logic and disable options before the feature becomes widely active. The source provides limited detail on implementation, so the full impact remains unverified.
