Tesla’s FSD V12.4.2 has landed in the wild – at least among early-access customers this week. There have been a few videos and some folks have begun to provide feedback on X, on the update and how it's going.
For now, it hasn’t gone wide to customers and only early-access testers and employees have it on their vehicles. FSD 12.4.2 is update 2024.15.10 and it’s expected to be available to everyone on update 2024.14 who owns or subscribes to FSD… eventually.
Consistent, Confident
Early-access testers have found FSD V12.4.2 to be considerably more confident, and more consistent when it makes decisions. V12.4.2 seems more confident when making unprotected left turns and encountering construction or complex interchanges.
They’ve also had more consistency and confidence with the Auto Speed feature, which adjusts the vehicle’s speed automatically based on traffic conditions, and also noted that it has improvements with lane selection, which was a larger issue in V12.4.1.
Users have also noted that the Vision-Based Driver Monitoring System is more confident and can see better at night. On V12.4.1, the Vision-Based DMS was unavailable at nighttime, and nags would still occur – but on V12.4.2, this restriction appears to be removed.
Regressions
There are still some regressions, with @DirtyTesLa on X noting that V12.4.2 seems to fail a left turn on an unmarked dirt road that it has previously made.
@WholeMarsBlog also noted that he had one critical safety intervention and that FSD missed a turn onto the highway, noting it was a regression from his experience on V12.4.1. Overall, he has had multiple intervention-free drives.
Overall Conclusions
It seems that besides a few minor regressions, V12.4.2 is shaping up to be a good update. There are improvements to the Vision-Based Driver Monitoring System, as well as improvements to decision-making and lane selection.
It is highly possible that V12.4.2 could be the version that unleashes the floodgates of nag-free FSD.
