FSD is slow to reach the correct lane after a ramp merge with turn-only lanes
Summary
With FSD engaged after merging onto a road via a ramp, the vehicle was slow to move from the right-turn-only lanes into the correct through lane; the curator also notes the section is poorly designed.
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 first two lanes after the ramp were right-turn only; the correct lane was the outermost.
- The vehicle did not move to the correct lane promptly.
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.
- How much the road layout versus the system's lane planning contributed.
