Watch Tesla’s “guardian angel” FSD feature take over for collision evasion

AI-summarised brief · reviewed before publication

Tesla’s Automatic Collision Evasion (ACE) feature, part of Full Self‑Driving (FSD) software, was demonstrated in a user‑posted video that showed the system re‑engaging FSD just before the driver’s vehicle struck a curb. The clip, shared by Tesla AI lead Ashok Elluswamy, illustrates ACE’s two trigger conditions: an imminent frontal crash on highways under 85 mph and a driver‑inattention scenario, such as reaching into the back seat. ACE is available only on HW4 hardware with an active FSD purchase or subscription and requires Automatic Emergency Braking to be enabled. The feature debuted in software update 2026.27.6 (FSD v14.3.9) and received refinements in subsequent builds 2026.27.10 and 2026.27.11. Tesla plans further safety upgrades in the upcoming FSD v15.

💡 Why It Matters

  • · ACE shows Tesla’s push to shift active safety from passive braking to autonomous steering, a step that could redefine driver responsibility in real‑time hazard avoidance.
