FSD does not yield to an ambulance before driver intervention
Summary
With FSD (Supervised) engaged, the vehicle did not perform the yielding response the driver judged necessary while an ambulance was present in surrounding traffic, and the driver took over control.
Written by White Box Autonomy from the sources listed below.
What is observable from the evidence
- An ambulance was present in the surrounding traffic environment.
- FSD (Supervised) was engaged during the interaction.
- Before driver intervention, the vehicle did not exhibit the yielding response the driver considered necessary.
- The driver intervened and took control.
- No collision occurred.
Automation status
Driving automation engaged — confirmed
Whether the driving-automation feature was engaged is a separate question from whether it caused the event.
System / software version
Not identified in the available sources.
Causal attribution
Undetermined
The available evidence does not establish a cause. Involvement of a driving-automation system is not the same as its being a cause.
What remains unknown
- Whether the system detected and correctly classified the ambulance.
- Whether emergency lights or a siren were active and clearly detectable from the evidence.
- Whether the system recognised a requirement to yield.
- What trajectory or behavioural prediction the system generated for the ambulance.
- Whether the system would eventually have yielded without intervention.
Interpretation
Curator interpretation — this goes beyond what the evidence directly shows
The event is consistent with an inadequate response to an emergency vehicle while driving automation was engaged. The available evidence establishes the externally observable behaviour and the driver intervention, but does not determine whether the limitation arose from perception, classification, behavioural prediction, right-of-way reasoning or motion planning.
