Tesla begins roll out of Autopilot Traffic Light and Stop Sign controls to early members
Tesla CEO Elon Musk has made good on his word to release the highly-anticipated Traffic Light and Stop Sign Control feature of Autopilot. Members of Tesla’s Early Access Program have begun reporting notifications of software release 2020.12.5.6, which includes the ability for Tesla’s Autopilot system to recognize and react to both traffic lights and stop signs. The feature appears to be the next step towards Tesla’s release of its “feature complete” Full Self-Driving suite.
It appears that Tesla is taking an extremely cautious approach with its Traffic Light and Stop Sign Control release, even if it’s only to members of the EAP. The release notes of the newly released feature indicate that vehicles will stop at each traffic light, including green, blinking yellow, and off lights. Drivers will be required to confirm the car’s navigation through traffic lights by pulling on the Autopilot stalk located behind the steering wheel or by pressing the accelerator.

Additionally, the feature will not complete turns through intersections. The function simply allows for safe navigation through intersections that are guided by traffic lights, an undoubtedly helpful feature that will likely be invaluable for inner-city driving, a key capability that’s needed for the release of a feature complete version of the FSD suite.
The feature is available for both Autosteer and Traffic-Aware Cruise Control. Both of these functions are available with Tesla’s current offering of basic Autopilot, which currently comes standard on all of the company’s vehicles save for the off-menu $35,000 Model 3 Standard Range.
The release notes for Traffic Light and Stop Sign Control (Beta) state:
“When Traffic-Aware Cruise Control or Autosteer is activated, Traffic Light and Stop Sign Control is designed to identify stop signs and traffic lights and automatically slow your car to a stop. When Traffic Light and Stop Sign Control is enabled, the driving visualization displays upcoming traffic lights, stop signs or road markings at intersections. As your car approaches an intersection, even one where a traffic light is green or off, your car will slow down and stop at the red line indicated. To continue through the stop line, push down the gear selector or briefly press the accelerator pedal to confirm that it is safe to proceed. As with all Autopilot features, you must continue to pay attention and be ready to take immediate action, including braking because this feature may not stop for all traffic controls.
To enable, shift your car into PARK and tap Controls > Autopilot > Traffic Light and Stop Sign Control (Beta).
Note: Before this feature can be enabled, camera calibration may be required, and the latest version of Navigation maps must be downloaded via Wi-Fi. Please refer to the Owner’s Manual for additional details about this feature.”
A few weeks ago, Elon Musk was questioned about the developments of the Traffic Light/Stop Sign recognition features. Musk stated that Tesla was, “Hoping to roll out traffic lights & stops to wide US release in a few weeks & probably WW release in Q3 (so many variations in each country!). Very important to make sure this is done right.”
Tesla’s addition of the Traffic Light and Stop Sign feature will not only improve the company’s Autopilot and Full Self-Driving functions; it also moves the company closer to having a “feature complete” version of the FSD suite. The next few weeks of data compiled from EAP members will assist Tesla’s Neural Network in understanding driver behavior at traffic lights and stop signs, increasing the safety of the company’s electric vehicles and allowing for a possible wide release soon.

Tesla is improving Giga Berlin’s free “Giga Train” service for employees
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
Tesla will expand its factory shuttle service in Germany beginning January 4, adding direct rail trips from Berlin Ostbahnhof to Giga Berlin-Brandenburg in Grünheide.
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
New shuttle route
As noted in a report from rbb24, the updated service, which will start January 4, will run between the Berlin Ostbahnhof East Station and the Erkner Station at the Gigafactory Berlin complex. Tesla stated that the timetable mirrors shift changes for the facility’s employees, and similar to before, the service will be completely free. The train will offer six direct trips per day as well.
“The service includes six daily trips, which also cover our shift times. The trains will run between Berlin Ostbahnhof (with a stop at Ostkreuz) and Erkner station to the Gigafactory,” Tesla Germany stated.
Even with construction continuing at Fangschleuse and Köpenick stations, the company said the route has been optimized to maintain a predictable 35-minute travel time. The update follows earlier phases of Tesla’s “Giga Train” program, which initially connected Erkner to the factory grounds before expanding to Berlin-Lichtenberg.
Tesla pushes for majority rail commuting
Tesla began production at Grünheide in March 2022, and the factory’s workforce has since grown to around 11,500 employees, with an estimated 60% commuting from Berlin. The facility produces the Model Y, Tesla’s best-selling vehicle, for both Germany and other territories.
The company has repeatedly emphasized its goal of having more than half its staff use public transportation rather than cars, positioning the shuttle as a key part of that initiative. In keeping with the factory’s sustainability focus, Tesla continues to allow even non-employees to ride the shuttle free of charge, making it a broader mobility option for the area.

Tesla Model 3 and Model Y dominate China’s real-world efficiency tests
The Tesla Model 3 posted 20.8 kWh/100 km while the Model Y followed closely at 21.8 kWh/100 km.
Tesla’s Model 3 and Model Y once again led the field in a new real-world energy-consumption test conducted by China’s Autohome, outperforming numerous rival electric vehicles in controlled conditions.
The results, which placed both Teslas in the top two spots, prompted Xiaomi CEO Lei Jun to acknowledge Tesla’s efficiency advantage while noting that his company’s vehicles will continue refining its own models to close the gap.
Tesla secures top efficiency results
Autohome’s evaluation placed all vehicles under identical conditions, such as a full 375-kg load, cabin temperature fixed at 24°C on automatic climate control, and a steady cruising speed of 120 km/h. In this environment, the Tesla Model 3 posted 20.8 kWh/100 km while the Model Y followed closely at 21.8 kWh/100 km, as noted in a Sina News report.
These figures positioned Tesla’s vehicles firmly at the top of the ranking and highlighted their continued leadership in long-range efficiency. The test also highlighted how drivetrain optimization, software management, and aerodynamic profiles remain key differentiators in high-speed, cold-weather scenarios where many electric cars struggle to maintain low consumption.

Xiaomi’s Lei Jun pledges to continue learning from Tesla
Following the results, Xiaomi CEO Lei Jun noted that the Xiaomi SU7 actually performed well overall but naturally consumed more energy due to its larger C-segment footprint and higher specification. He reiterated that factors such as size and weight contributed to the difference in real-world consumption compared to Tesla. Still, the executive noted that Xiaomi will continue to learn from the veteran EV maker.
“The Xiaomi SU7’s energy consumption performance is also very good; you can take a closer look. The fact that its test results are weaker than Tesla’s is partly due to objective reasons: the Xiaomi SU7 is a C-segment car, larger and with higher specifications, making it heavier and naturally increasing energy consumption. Of course, we will continue to learn from Tesla and further optimize its energy consumption performance!” Lei Jun wrote in a post on Weibo.
Lei Jun has repeatedly described Tesla as the global benchmark for EV efficiency, previously stating that Xiaomi may require three to five years to match its leadership. He has also been very supportive of FSD, even testing the system in the United States.

Elon Musk reveals what will make Optimus’ ridiculous production targets feasible
Musk recent post suggests that Tesla has a plan to attain Optimus’ production goals.
Elon Musk subtly teased Tesla’s strategy to achieve Optimus’ insane production volume targets. The CEO has shared his predictions about Optimus’ volume, and they are so ambitious that one would mistake them for science fiction.
Musk’s recent post on X, however, suggests that Tesla has a plan to attain Optimus’ production goals.
The highest volume product
Elon Musk has been pretty clear about the idea of Optimus being Tesla’s highest-volume product. During the Tesla 2025 Annual Shareholder Meeting, Musk stated that the humanoid robot will see “the fastest production ramp of any product of any large complex manufactured product ever,” starting with a one-million-per-year line at the Fremont Factory.
Following this, Musk stated that Giga Texas will receive a 10 million-per-year unit Optimus line. But even at this level, the Optimus ramp is just beginning, as the production of the humanoid robot will only accelerate from there. At some point, the CEO stated that a Mars location could even have a 100 million-unit-per-year production line, resulting in up to a billion Optimus robots being produced per year.
Self-replication is key
During the weekend, Musk posted a short message that hinted at Tesla’s Optimus strategy. “Optimus will be the Von Neumann probe,” the CEO wrote in his post. This short comment suggests that Tesla will not be relying on traditional production systems to make Optimus. The company probably won’t even hire humans to produce the humanoid robot at one point. Instead, Optimus robots could simply produce other Optimus robots, allowing them to self-replicate.
The Von Neumann is a hypothetical self-replicating spacecraft proposed by the mathematician and physicist John von Neumann in the 1940s–1950s. The hypothetical machine in the concept would be able to travel to a new star system or location, land, mine, and extract raw materials from planets, asteroids, and moons as needed, use those materials to manufacture copies of itself, and launch the new copies toward other star systems.
If Optimus could pull off this ambitious target, the humanoid robot would indeed be the highest volume product ever created. It could, as Musk predicted, really change the world.
