Tesla has included in its latest software update in North America a new safety feature that suggests activating Full Self Driving (FSD) Supervised when it detects signs of drowsiness or lane drift.
The information was first revealed by the X user ‘greentheonly,’ who frequently shares technical insights about upcoming Tesla vehicles or hidden features in software updates.
With the latest software update — 2025.32.3 — which started being rolled out on September 2, the drowsiness/lane departure alerts now prompt the driver to “stay focused” with FSD.
“Hm, interesting messaging shift in 2025.32.3. Now the drowsiness/lane departure alerts suggest FSD,” he wrote on X.
The system alerts now say “Lane drift detected. Let FSD assist so you can stay focused,” or “Drowsiness detected. Stay focused with FSD.”
On top of both alerts, Tesla‘s assisted driving technology “requires a fully attentive driver and will display a series of escalating warnings requiring driver response.”
However, the goal is for the FSD to be a fully autonomous system in the near future.
According to Elon Musk, Tesla vehicles “will be sentient by the end of the year” as the company launches the 14th version of the software.
Last month, Musk had written on X a list of upcoming main events across his companies, where it was included that the V14 would be released “also next month.”
However, it was pushed back to the end of the year.
The company is already testing fully autonomous driving with its driverless ride-hailing service, launched in Austin in late June, through invitation-only at first.
As Tesla expands its Robotaxi to several other states and to the general public, the vehicles still requires the presence of a safety operator.
In Austin, operators sit in the passenger seat. To comply with the regulations, when trips include driving on the freeway, the safety operator should sit behind the wheel.
In the Bay Area, where autonomous driving regulations are stricter, they are always in the driver’s seat.
This makes the service look more like a regular ride-hailing trip, where the driver simply owns a Tesla and is using its Supervised FSD feature.
Late last week, Musk wrote on X that “the safety driver is only needed for the first few months to be extra safe” and “there should be no safety driver by the end of the year.”
Last week, Tesla‘s VP of Engineering Lars Moravy said that customers purchasing the new Model S and Model X have opted to buy the FSD — at $8,000 in a single payment, instead of subscribing to the service for $99 per month.
According to the executive, the FSD take rate for the flagship models was 50-60% in the past few months, before the release of the ‘Luxe Package’ last month, which now includes the FSD as part of the purchase.
