Elon Musk explains rationale behind Twitter’s weekly work update rule
Recent reports have revealed that Elon Musk and his team have rolled out a new rule for Twitter employees. Every week, Twitter’s employees will be expected to submit a weekly summary of what they worked on, what they are trying to accomplish, and specific lines of code that they wrote.
The new rule was announced through an email from Twitter Engineering, a department that is reportedly led personally by Musk. The message was reportedly sent following another all-hands meeting where Musk stated that no more layoffs are coming for now, and there are currently no plans to move Twitter’s headquarters to Texas. Several of Musk’s key companies are based in Texas, such as Tesla and SpaceX.
Amidst the reports, Musk noted on Twitter that the rule is simply a way to know if anything was accomplished. “Perhaps not unreasonable to know if anything was accomplished,” Musk wrote on Twitter.
Considering the text of Musk’s message, it would seem like Twitter’s remaining employees are safe for now, though the following weeks and months would likely be challenging. Musk’s demands, including the weekly reports, may seem extensive, but they do reflect equally-intensive strategies that were adopted at his other companies like Tesla. There is a reason why Musk has dubbed himself a “nanomanager,” after all.
Following is the text of Musk’s email.
Subject line: Weekly Software/Technical Updates
Twitter Team,
In order to innovate rapidly on software, it is critical to understand what everyone is working on and who is coding what.
Moving forward, every Friday (this week, on Wednesday), please email the following weekly update to xxxxxxxxx@twitter.com with the following format:
-Subject line: “Weekly Update, name, dept, and date (eg “Weekly Update, John smith, SWE, 11/20)
-Email Body:
- What project you are working on (eg Blue Verified)
- What you are trying to accomplish (eg reliably collect the $8 payment)
- Code Samples/Phabricator links of code written that week
This weekly update applies to:
- All managers/engineers in SWE and ML
- Anyone who should be writing code in other departments, such as SRE and Network
- For technical positions where code is not written (eg network/database admin), replace “Code samples/Phabricator links” above with “Summary of work”
- For technical positions where code is not written and analyses are being performer (eg data scientist), replace “Code sample/Phabricator links” with “Summary and results of analysis”
If there are any questions or ambiguity, please email xxxxxxxxx@twitter.com.
Looking forward to making Twitter the highest performing tech software company in the world.
Twitter Engineering
Despite concerns over the past week that Twitter would collapse as large numbers of its employees quit or were terminated, the social media platform has continued to operate like before. Estimates suggest that for now, Twitter has about 2,300 full-time employees, a notable drop from the 7,500 when Musk took over the company. Twitter, for its part, has started initiating welcome changes, such as the destruction of hashtags used by suspected child predators and an easier reporting system for harmful content for children, among others.

Tesla Model Y L is gaining momentum in China’s premium segment
This suggests that the addition of the Model Y L to Tesla China’s lineup will not result in a case of cannibalization, but a possible case of “premiumization” instead.
Tesla’s domestic sales in China held steady in November with around 73,000 units delivered, but a closer look at the Model Y L’s numbers hints at an emerging shift towards pricier variants that could very well be boosting average selling prices and margins.
This suggests that the addition of the Model Y L to Tesla China’s lineup will not result in a case of cannibalization, but a possible case of “premiumization” instead.
Tesla China’s November domestic numbers
Data from the a Passenger Car Association (CPCA) indicated that Tesla China saw domestic deliveries of about 73,000 vehicles in November 2025. This number included 34,000 standard Model Y units, 26,000 Model 3 units, and 13,000 Model Y L units, as per industry watchers.
This means that the Model Y L accounted for roughly 27% of Tesla China’s total Model Y sales, despite the variant carrying a ~28% premium over the base RWD Model Y that is estimated to have dominated last year’s mix.
As per industry watcher @TSLAFanMtl, this suggests that Tesla China’s sales have moved towards more premium variants this year. Thus, direct year-over-year sales comparisons might miss the bigger picture. This is true even for the regular Model Y, as another premium trim, the Long Range RWD variant, was also added to the lineup this 2025.
November 2025 momentum
While Tesla China’s overall sales this year have seen challenges, the Model Y and Model 3 have remained strong sellers in the country. This is especially impressive as the Model Y and Model 3 are premium-priced vehicles, and they compete in the world’s most competitive electric vehicle market. Tesla China is also yet to roll out the latest capabilities of FSD in China, which means that its vehicles in the country could not tap into their latest capabilities yet.
Aggregated results from November suggest that the Tesla Model Y took the crown as China’s #1 best-selling SUV during the month, with roughly 34,000 deliveries. With the Model Y L, this number is even higher. The Tesla Model 3 also had a stellar month, seeing 25,700 deliveries during November 2025.

Tesla Cybertruck earns IIHS Top Safety Pick+ award
To commemorate the accolade, the official Cybertruck account celebrated the milestone on X.
The Tesla Cybertruck has achieved the Insurance Institute for Highway Safety’s (IIHS) highest honor, earning a Top Safety Pick+ rating for 2025 models built after April 2025.
The full-size electric pickup truck’s safety rating is partly due to the vehicle’s strong performance in updated crash tests, superior front crash prevention, and effective headlights, among other factors. To commemorate the accolade, the official Cybertruck account celebrated the milestone on X.
Cybertruck’s IIHS rating
As per the IIHS, beginning with 2025 Cybertruck models built after April 2025, changes were made to the front underbody structure and footwell to improve occupant safety in driver-side and passenger-side small overlap front crashes. The moderate overlap front test earned a good rating, and the updated side impact test also received stellar marks.
The Cybertruck’s front crash prevention earned a good rating in pedestrian scenarios, with the standard Collision Avoidance Assist avoiding collisions in day and night tests across child, adult crossing, and parallel paths. Headlights with high-beam assist compensated for limitations, contributing to the top award.
Safest and most autonomous pickup
The Cybertruck is one of only two full-size pickups to receive the IIHS’ Top Safety Pick + rating. It is also the only one equipped with advanced self-driving features via Tesla’s Full Self-Driving (Supervised) system. Thanks to FSD, the Cybertruck can navigate inner city streets and highways on its own with minimal supervision, adding a layer of safety beyond passive crash protection.
Community reactions poured in, with users praising the vehicle’s safety rating amidst skepticism from critics. Tesla itself highlighted this by starting its X post with a short clip of a Cybertruck critic who predicted that the vehicle will likely not pass safety tests. The only question now is, of course, if the vehicle’s Top Safety Pick+ rating from the IIHS will help the Cybertruck improve its sales.

Tesla stands to gain from Ford’s decision to ditch large EVs
Tesla is perhaps the biggest beneficiary of Ford’s decision, especially as it will no longer have to deal with the sole pure EV pickup that outsold it from time to time: the F-150 Lightning.
Ford’s recent decision to abandon production of the all-electric Ford F-150 Lightning after the 2025 model year should yield some advantages for Tesla.
The Detroit-based automaker’s pivot away from large EVs and toward hybrids and extended-range EVs that come with a gas generator is proof that sustainable powertrains are easy on paper, but hard in reality.
Tesla is perhaps the biggest beneficiary of Ford’s decision, especially as it will no longer have to deal with the sole pure EV pickup that outsold it from time to time: the F-150 Lightning.
Here’s why:
Reduced Competition in the Electric Pickup Segment
The F-150 Lightning was the Tesla Cybertruck’s primary and direct rival in the full-size electric pickup market in the United States. With Ford’s decision to end pure EV production of its best-selling truck’s electric version and shifting to hybrids/EREVs, the Cybertruck faces significantly less competition.

This could drive more fleet and retail buyers toward the Cybertruck, especially those committed to fully electric vehicles without a gas generator backup.
Strengthened Market Leadership and Brand Perception in Pure EVs
Ford’s pullback from large EVs–citing unprofitability and lack of demand for EVs of that size–highlights the challenges legacy automakers face in scaling profitable battery-electric vehicles.
Tesla, as the established leader with efficient production and vertical integration, benefits from reinforced perception as the most viable and committed pure EV manufacturer.

This can boost consumer confidence in Tesla’s long-term ecosystem over competitors retreating to hybrids. With Ford making this move, it is totally reasonable that some car buyers could be reluctant to buy from other legacy automakers.
Profitability is a key reason companies build cars; they’re businesses, and they’re there to make money.
However, Ford’s new strategy could plant a seed in the head of some who plan to buy from companies like General Motors, Stellantis, or others, who could have second thoughts. With this backtrack in EVs, other things, like less education on these specific vehicles to technicians, could make repairs more costly and tougher to schedule.
Potential Increases in Market Share for Large EVs
Interestingly, this could play right into the hands of Tesla fans who have been asking for the company to make a larger EV, specifically a full-size SUV.
Customers seeking large, high-capability electric trucks or SUVs could now look to Tesla for its Cybertruck or potentially a future vehicle release, which the company has hinted at on several occasions this year.
With Ford reallocating resources away from large pure EVs and taking a $19.5 billion charge, Tesla stands to capture a larger slice of the remaining demand in this segment without a major U.S. competitor aggressively pursuing it.
