FSD Version History › FSD 12.4
Tesla FSD 12.4
Overview
FSD 12.4 advances the end-to-end V12 neural planner with targeted improvements in roundabout handling, unprotected turns, and lane selection on multi-lane arterials.
What's new in FSD 12.4
- Better roundabout entry, navigation, and exit logic
- Improved unprotected left turn gap acceptance
- More accurate lane selection on wide multi-lane roads
- Smoother speed modulation through curves
- Improved response to stop signs in rural settings
Known issues
- Edge cases in dense urban parking lots still require intervention
- Some reports of incorrect lane selection near complex interchanges
Community feedback
Users note tangible improvement in turn-handling confidence. FSD 12.4 marks the point where many owners begin daily unsupervised-style use (while still legally required to supervise).
