Tesla FSD 12.4 will fix lane change issues

Tesla will release a new fix for FSD testers facing issues with the lane change feature, which is one of the essential capabilities of this self-driving technology.

Full Self-driving (FSD) enables Tesla cars to drive automatically with the help of artificial intelligence (AI) and large models. FSD facilitates capabilities such as navigating interchanges, automatically enabling turn signals, and taking a correct exit.

Its automatic lane change enables Tesla to change lanes on its own. It requires enabling Auto Lane Change from the Autopilot Controls menu from the Settings tab.

The latest FSD 12 version has strengthened its capabilities to navigate through traffic and made it more consistent with end-to-end neural networks. However, it still has a few bugs which appear with new builds.

Prominent FSD user @WholeMarsBlog shared a bug on social media site X, formerly known as Twitter, saying that the 12.3.5 version is generating issues in changing lanes.

“FSD 12.3.5 can never just change lanes. It has to start changing lanes, then come back to the original lane, then change lanes slowly. It’s super annoying” explains the tester.

Last week, Tesla released FSD (Supervised) version 12.3.5, an improvement and software fix update. The company is currently expanding this software for FSD testers.

FSD 12.4

Elon Musk, CEO of Tesla has replied to the corresponding tester. Musk said this issue is fixed in version 12.4, which is yet to be released. He also mentioned that the version 12.3.x series brings minor changes to the FSD ecosystem.

The Tesla chief gave similar remarks last week on X mentioning that the 12.4 will be a major release and should be called FSD 13 instead. These comments from Musk came without revealing any details on features and new additions.

Tesla is releasing these new software updates to FSD to improve its user experience. It is expected that the company will back-end this technology into the Robotaxi product and it will guide the overall navigation.
