A select bunch of Tesla owners have received a new Autopilot feature that allows the marque’s vehicles to stop at traffic lights without any driver intervention.

Electrek reports that this feature forms part of a more advanced version of Autopilot that Tesla is developing for suburban driving. A video shared on Twitter shows the owner of a Model 3 filming the electric sedan reacting to traffic lights.

Tesla rolls out such new software features to its ‘early access fleet’, a group of owners who have the opportunity to test out new updates from the automaker before they’re introduced to the market. This video shows how the Tesla is able to set off when the traffic light turns green (albeit with a slight delay) and how it can bring the car to a stop at a red light, even with no vehicle in front to follow.

The tech doesn’t seem to work flawlessly, however. On three occasions, the system says it will stop for an upcoming traffic light a few hundred feet ahead, before realizing those lights are green and that it can continue through the intersection.

Nevertheless, the system does correctly notify the driver of a red light 500 feet up the road and around a slight left-hand bend. As a piece of beta software, it appears to work quite well.

It remains to be seen when this software update could be pushed through to all Tesla owners. When it does, owners should be reminded that Autopilot is only a driver-assistance system and that they need to remain attentive at all times and be prepared to take over control whenever necessary.
