Summary

On the first day of using a newly updated version of Tesla FSD (Supervised), with automation engaged, the vehicle moved from side to side repeatedly over a short period in a way inconsistent with holding a stable path.

Written by White Box Autonomy from the sources listed below.

What is observable from the evidence

  • The event occurred during the first day of using a newly updated version of Tesla FSD (Supervised).
  • Driving automation was engaged.
  • The vehicle moved laterally from side to side.
  • The lateral movement repeated during a short period.
  • The behaviour was inconsistent with maintaining a stable roadway path.
  • No collision occurred in the recorded event.

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

  • The perception, localisation, planning or control process associated with the oscillation.
  • Whether road geometry, lane markings, localisation, surrounding traffic or other environmental conditions contributed.
  • Whether the behaviour would have continued without intervention.
  • The exact lateral displacement and safety margin.
  • The exact software version in use.

Interpretation

Curator interpretation — this goes beyond what the evidence directly shows

The repeated lateral movement is consistent with unstable or inappropriate path control during automated driving. The available video can document the observable weaving, but it cannot establish which subsystem or environmental factor caused the behaviour.
