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.

SpaceX issues statement on Starship V3 Booster 18 anomaly
The incident unfolded during gas-system pressure testing at the company’s Massey facility in Starbase, Texas.
SpaceX has issued an initial statement about Starship Booster 18’s anomaly early Friday. The incident unfolded during gas-system pressure testing at the company’s Massey facility in Starbase, Texas.
SpaceX’s initial comment
As per SpaceX in a post on its official account on social media platform X, Booster 18 was undergoing gas system pressure tests when the anomaly happened. Despite the nature of the incident, the company emphasized that no propellant was loaded, no engines were installed, and personnel were kept at a safe distance from the booster, resulting in zero injuries.
“Booster 18 suffered an anomaly during gas system pressure testing that we were conducting in advance of structural proof testing. No propellant was on the vehicle, and engines were not yet installed. The teams need time to investigate before we are confident of the cause. No one was injured as we maintain a safe distance for personnel during this type of testing. The site remains clear and we are working plans to safely reenter the site,” SpaceX wrote in its post on X.
Incident and aftermath
Livestream footage from LabPadre showed Booster 18’s lower half crumpling around the liquid oxygen tank area at approximately 4:04 a.m. CT. Subsequent images posted by on-site observers revealed extensive deformation across the booster’s lower structure. Needless to say, spaceflight observers have noted that Booster 18 would likely be a complete loss due to its anomaly.
Booster 18 had rolled out only a day earlier and was one of the first vehicles in the Starship V3 program. The V3 series incorporates structural reinforcements and reliability upgrades intended to prepare Starship for rapid-reuse testing and eventual tower-catch operations. Elon Musk has been optimistic about Starship V3, previously noting on X that the spacecraft might be able to complete initial missions to Mars.

Tesla analyst maintains $500 PT, says FSD drives better than humans now
The team also met with Tesla leaders for more than an hour to discuss autonomy, chip development, and upcoming deployment plans.
Tesla (NASDAQ:TSLA) received fresh support from Piper Sandler this week after analysts toured the Fremont Factory and tested the company’s latest Full Self-Driving software. The firm reaffirmed its $500 price target, stating that FSD V14 delivered a notably smooth robotaxi demonstration and may already perform at levels comparable to, if not better than, average human drivers.
The team also met with Tesla leaders for more than an hour to discuss autonomy, chip development, and upcoming deployment plans.
Analysts highlight autonomy progress
During more than 75 minutes of focused discussions, analysts reportedly focused on FSD v14’s updates. Piper Sandler’s team pointed to meaningful strides in perception, object handling, and overall ride smoothness during the robotaxi demo.
The visit also included discussions on updates to Tesla’s in-house chip initiatives, its Optimus program, and the growth of the company’s battery storage business. Analysts noted that Tesla continues refining cost structures and capital expenditure expectations, which are key elements in future margin recovery, as noted in a Yahoo Finance report.
Analyst Alexander Potter noted that “we think FSD is a truly impressive product that is (probably) already better at driving than the average American.” This conclusion was strengthened by what he described as a “flawless robotaxi ride to the hotel.”
Street targets diverge on TSLA
While Piper Sandler stands by its $500 target, it is not the highest estimate on the Street. Wedbush, for one, has a $600 per share price target for TSLA stock.
Other institutions have also weighed in on TSLA stock as of late. HSBC reiterated a Reduce rating with a $131 target, citing a gap between earnings fundamentals and the company’s market value. By contrast, TD Cowen maintained a Buy rating and a $509 target, pointing to strong autonomous driving demonstrations in Austin and the pace of software-driven improvements.
Stifel analysts also lifted their price target for Tesla to $508 per share over the company’s ongoing robotaxi and FSD programs.

SpaceX Starship Version 3 booster crumples in early testing
Photos of the incident’s aftermath suggest that Booster 18 will likely be retired.
SpaceX’s new Starship first-stage booster, Booster 18, suffered major damage early Friday during its first round of testing in Starbase, Texas, just one day after rolling out of the factory.
Based on videos of the incident, the lower section of the rocket booster appeared to crumple during a pressurization test. Photos of the incident’s aftermath suggest that Booster 18 will likely be retired.
Booster test failure
SpaceX began structural and propellant-system verification tests on Booster 18 Thursday night at the Massey’s Test Site, only a few miles from Starbase’s production facilities, as noted in an Ars Technica report. At 4:04 a.m. CT on Friday, a livestream from LabPadre Space captured the booster’s lower half experiencing a sudden destructive event around its liquid oxygen tank section. Post-incident images, shared on X by @StarshipGazer, showed notable deformation in the booster’s lower structure.
Neither SpaceX nor Elon Musk had commented as of Friday morning, but the vehicle’s condition suggests it is likely a complete loss. This is quite unfortunate, as Booster 18 is already part of the Starship V3 program, which includes design fixes and upgrades intended to improve reliability. While SpaceX maintains a rather rapid Starship production line in Starbase, Booster 18 was generally expected to validate the improvements implemented in the V3 program.
Tight deadlines
SpaceX needs Starship boosters and upper stages to begin demonstrating rapid reuse, tower catches, and early operational Starlink missions over the next two years. More critically, NASA’s Artemis program depends on an on-orbit refueling test in the second half of 2026, a requirement for the vehicle’s expected crewed lunar landing around 2028.
While SpaceX is known for diagnosing failures quickly and returning to testing at unmatched speed, losing the newest-generation booster at the very start of its campaign highlights the immense challenge involved in scaling Starship into a reliable, high-cadence launch system. SpaceX, however, is known for getting things done quickly, so it would not be a surprise if the company manages to figure out what happened to Booster 18 in the near future.
