What is observable from the evidence
- FSD was engaged (curator's first-hand account).
- The left-turn signal went green; the vehicle stayed stopped.
- The display briefly showed a right-turn indication; the vehicle turned left after driver accelerator input.
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
13.2.9
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
- The exact day within April 2026.
- Whether the wrong-direction indication reflected an internal planning conflict — HMI display is not proof of internal state.
