Written by White Box Autonomy from the sources listed below.
What is observable from the evidence
- FSD was engaged (curator's first-hand account).
- The road's posted limit was 50 km/h; the display showed 30 km/h.
- Raising the set speed toward 50 km/h triggered a red warning on the display.
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 March 2026.
- Whether the internal speed model matched the display — HMI display is not proof of internal state.
