Tesla has made some significant improvements with FSD 12.4, primarily, the removal of the steering wheel nag under certain conditions. However, there’s a caveat – you can’t wear sunglasses.
According to Elon Musk, FSD v12.5 will introduce support for nag-free FSD, even if you’re wearing sunglasses.
With the start of the rollout of FSD v12.5, OG testers immediately noticed that vision monitoring didn’t support sunglasses. Ashok Elluswamy, Tesla’s Autopilot Director commented on the FSD release and mentioned that the merge of city and highway stacks and vision-monitoring’s support for sunglasses would come in a point release to FSD 12.5.
FSD V12.5 is an Upgrade
Ashok Elluswamy also took to X recently to mention that v12.5 is a big improvement to FSD v12.4. While he didn’t mention any specific details, this lines up with some of Musk’s previous comments that each FSD v12 iteration will see major improvements to the FSD model.
Elon also mentioned that while Tesla has a massive fleet of cars, their laser focus on making FSD work, rather than touting every daily achievement – has been their key to making generalized self-driving cars work.
FSD v12 has been pretty much a complete rewrite of the FSD city streets software stack, with drastic improvements over FSD v11. However, certain parts of the software stack haven’t been updated yet. Some features, like the updated highway stack are expected to be in FSD v12.5, which Musk confirmed recently. However, other features such as Park Seek and Banish Autopark, which were expected to arrive with FSD V12.4 are still up in the air.
What about V12.4?
FSD V12.4.3 is currently out to about 5% of the fleet (about 20-25% of FSD users) and hasn’t been pushed out again since about July 10th. Our new auto updating statistics pages can help break this down for folks who are curious.

Given that it’s been some time since any new vehicles have received V12.4.3, it seems the rollout has been stopped. There could be any number of reasons for this – including software bugs, or a lack of confidence with FSD. Additionally, it could just halted in favor of focusing resources on V12.5.
While we’d love to see more vehicles get v12.4.3, we’re likely to see v12.5 being the next big wave of deployments to customers. Either way, early-access testers and Tesla ADAS testers will receive these updates first, and then they’ll roll out to the vast majority of customers once Tesla feels confident there aren’t any major issues. Tesla does all this testing in the name of safety, and it's essential that bug-free versions of FSD are the versions that are rolled out wide.
So, for now, leave your sunglasses on and hang tight for the next FSD update.
