Over 1,700 Tesla investors are responding to Elizabeth Warren’s call for Musk investigation
Over 1,700 Tesla shareholders are responding to Massachusetts Senator Elizabeth Warren, who recently wrote a letter to Tesla Board Chair Robyn Denholm asking the EV maker’s Board of Directors to investigate CEO Elon Musk’s alleged conflicts of interest. As per the Tesla shareholders, the US Senator’s efforts are better directed towards matters that directly relate to her home state.
US Senator Warren’s letter to the Tesla Board of Directors was made public last week. The official outlined several concerns in her letter, such as Musk’s alleged diversion of Tesla’s resources to xAI, his alleged conflicts of interest, and the alleged neglect of corporate governance duties from the Tesla Board of Directors. Warren also argued that Tesla shareholders have “suffered” from a lack of oversight at the EV maker.
In their response, the TSLA shareholders noted that they are concerned about the US official’s focus on Tesla, especially since the EV maker is not domiciled in Massachusetts. The stockholders, who number over 1,700 as of a recent update, also addressed some of the US Senator’s concerns in her letter.

Following is the Tesla stockholders’ letter to US Senator Warren.
Dear Senator Warren,
We, the undersigned Tesla shareholders, are writing in response to your letter dated August 8, 2024, addressed to Dr. Robyn Denholm, Chair of the Board of Tesla. We must express our deep concern and disappointment regarding your unwarranted interference in Tesla’s affairs.
First and foremost, we question the basis of your involvement in this matter. Tesla is not domiciled in your state, and to our knowledge, you are not a shareholder. Your attempt to exert influence over a company in which you have no direct stake is, frankly, perplexing and concerning.
We cannot help but view your actions as politically motivated, particularly given the timing of your letter during a Presidential election period. This appears to be an attempt to generate political pressure rather than a genuine effort to address shareholder concerns.
Your letter conspicuously fails to acknowledge Tesla’s significant contributions to the American economy, the global shift to EVs and to a sustainable future. As the most American car maker, Tesla has created tens of thousands of jobs across the country. Moreover, Elon Musk’s other ventures have further bolstered American innovation and employment. Your silence on these crucial points is telling.
Addressing Your Specific Points:
1. Diversion of Al Resources: The allocation of resources across Musk’s companies often leads to synergies that benefit Testa. This is a matter for the Board and shareholders to address, not external politicians.
2. Founding of xAI: The potential for collaboration between XAl and Tesla could drive innovation in ways that ultimately benefit our company and shareholders.
3. Conflicts of Interest: The Board is well aware of its fiduciary duties and is capable of managing potential conflicts without external political pressure.
4. Board’s Oversight: We have confidence in our Board’s ability to provide appropriate oversight. Your assertions of failure are both premature and presumptuous.
5. Shareholder Concerns: While some concerns exist, many shareholders continue to support Mr. Musk’s vision and leadership. We prefer to address these matters internally, without political interference.
6. Your Questions: While your questions are noted, we believe they should be addressed to the Board by legitimate stakeholders, not by politicians seeking to make headlines.
Senator Warren, while we respect your role as a public servant, we strongly believe your energies would be better directed towards matters that fall within your purview as a Senator from Massachusetts.
Testa’s corporate governance is a matter for its Board, its shareholders, and the appropriate regulatory bodies.
We kindly request that you refrain from further interference in Tesla’s affairs. Instead, we suggest focusing on creating an environment that fosters innovation and job creation – areas where Tesla and Elon Musk’s other ventures have demonstrably excelled.
We stand firmly behind Testa’s mission and leadership, and we will continue to work constructively with the Board to ensure the company’s ongoing success and adherence to proper governance standards.
Sincerely,
Tesla Shareholders
This is not the first time that Tesla or Musk has found itself in the crosshairs of the US Senator. Back in December 2021, Warren called for changes in the US tax code so that Elon Musk would stop “freeloading off everyone else.” In December 2022, Warren sent a letter to Tesla’s Board of Directors asking them if Elon Musk has been diverting the EV maker’s resources to Twitter. In July 2023, Warren also sent a letter encouraging the SEC to investigate Tesla and its Board of Directors, citing potential “conflicts of interest, misappropriation of corporate assets, and other negative impacts to Tesla shareholders” related to Elon Musk’s acquisition of social media platform Twitter.

Tesla has taken home the “Overall Loyalty to Make” award from S&P Global Mobility for the fourth consecutive year, reinforcing Tesla owners’ willingness to come back. The 2025 awards are based on S&P Global Mobility’s analysis of 13.6 million new retail vehicle registrations in the U.S. from October 2024 through September 2025. The complete list of 2025 winners includes General Motors for Overall Loyalty to Manufacturer, Tesla for Overall Loyalty to Make, Chevrolet Equinox for Overall Loyalty to Model, Mini for Most Improved Make Loyalty, Subaru for Overall Loyalty to Dealer, and Tesla again for both Ethnic Market Loyalty to Make and Highest Conquest Percentage.
Tesla’s streak in this category started in 2022, and the brand has now won the Highest Conquest Percentage award for six straight years, meaning it keeps pulling buyers away from other brands at a rate no competitor has matched. Tesla’s retention among Asian households reached 63.6% and among Hispanic households 61.9%, rates that significantly outpace national averages for those groups. That breadth of appeal across demographics adds a layer of significance to a win that some might dismiss as routine.
The timing matters too. After several consecutive quarters of decline, Tesla’s share of U.S. EV sales jumped to 59% in Q4 2025. That rebound, arriving just as competitors were flooding the market with new models and incentives, suggests Tesla’s loyalty numbers are not simply the result of limited alternatives. Buyers are still choosing it when they have plenty of other options.
What keeps Tesla owners coming back has a lot to do with the and convenience of charging. The Supercharger network is the most straightforward example. With over 65,000 Superchargers globally, it remains the largest and most reliable fast-charging network in the world, and owners who have built their routines around it face a real practical cost when considering a switch. Competitors have made progress, but the consistency, speed, and availability of Tesla’s network is still the benchmark the rest of the industry is chasing. Then there is the software side. Tesla has built a model where the car you own today is functionally different from the car you bought two years ago, through over-the-air updates that add continuous game-changing improvements such as Full Self-Driving that has moved from a driver-assist feature to an increasingly capable autonomous system. For many Tesla owners, leaving the brand means starting over with a car that will not get meaningfully better over time, and that is a trade-off fewer and fewer are willing to make.
Tesla Robotaxi services in Austin have been operating since last Summer, but Tesla has admittedly been delayed in its expansion of the geofence, fleet size, and other details in a bid to prioritize safety as new technology rolls out.
But those barriers are being broken with new guardrails being removed from the program.
Tesla has achieved a significant advancement in its autonomous ride-hailing program. As of May 4, the Robotaxi fleet in Austin, Texas, has begun operating unsupervised during evening hours for the first time. This expansion moves beyond previous limitations that restricted unsupervised service to daylight hours, typically ending in mid-afternoon.

The change brings Austin in line with operations in Dallas and Houston. Those cities have supported evening unsupervised runs since their initial launches in April, and both recently received additions of new unsupervised vehicles to their fleets. This coordinated progress across Texas strengthens Tesla’s regional presence and provides a broader testing ground for the technology.
This milestone carries substantial weight in the development of autonomous vehicles. Extending operations into low-light conditions meaningfully expands the Robotaxi’s operational design domain (ODD)—the specific environments and scenarios in which the system is approved to operate safely without human intervention.
Nighttime driving presents unique technical demands: diminished visibility, headlight glare from oncoming traffic, reduced contrast for identifying pedestrians and lane markings, and greater variability in camera sensor exposure.
Tesla’s pure vision approach, powered by neural networks trained on vast real-world datasets rather than lidar or pre-mapped routes, must handle these variables reliably. Demonstrating consistent unsupervised performance after sunset validates the robustness of the end-to-end AI stack and its ability to generalize across diverse lighting conditions.
Beyond technical validation, the expansion holds important operational and economic implications. Evening hours often coincide with peak urban demand for rides, including commutes, dining, and entertainment outings.
Enabling service during these periods increases daily vehicle utilization, allowing each Robotaxi to generate more revenue while gathering additional high-value training data. Higher utilization accelerates the virtuous cycle of data collection, model improvement, and further ODD growth.
Looking ahead, this step paves the way for more ambitious rollouts. Success in low-light environments positions Tesla to pursue near-24-hour operations, potentially integrating highways and expanding into varied weather patterns. Regulators worldwide frequently demand evidence of safe performance across day-night cycles before granting wider approvals.
Proven capability in Texas could expedite deployments in planned cities such as Phoenix, Miami, Orlando, Tampa, and Las Vegas during the first half of 2026.

Moreover, scaling evening service supports Tesla’s long-term vision of a high-efficiency robotaxi network. Greater fleet productivity lowers the cost per mile, making autonomous mobility more accessible and competitive against traditional ride-hailing.
As the company iterates on software updates informed by nighttime data, reliability is expected to compound rapidly, unlocking denser urban coverage and longer-distance trips.
In summary, the introduction of an unsupervised evening Robotaxi service in Austin represents more than an incremental schedule adjustment. It signals a critical maturation of the underlying technology and sets the foundation for broader geographic and temporal expansion.
With Texas operations gaining momentum, Tesla is steadily advancing toward transforming urban transportation at scale.

Tesla Cybercab just rolled through Miami inside a glass box
Tesla paraded a Cybercab in a glass display at Miami’s F1 Grand Prix event this week.
Tesla set up an “Autonomy Pop-Up” at Lummus Park in Miami Beach from April 29 through May 3, 2026, embedded within the official F1 Miami Grand Prix Fan Fest. The centerpiece was a Cybertruck towing the Cybercab inside a glass display case marked “Future is Autonomous,” rolling through the beachfront crowd.
Miami is on Tesla’s confirmed list of cities for robotaxi expansion in the first half of 2026, making the promotion a strategic promotion that lays groundwork in a target market.
This was not Tesla’s first time using Miami as a showcase city. In December 2025, Tesla hosted “The Future of Autonomy Visualized” at its Miami Design District showroom, coinciding with Art Basel Miami Beach. That event featured the Cybercab prototype and Optimus robots interacting with attendees. The F1 pop-up this week marks Tesla’s return to Miami and follows a pattern Tesla has been running since early 2026. Just two weeks before Miami, Tesla stationed Optimus at the Tesla Boston Boylston Street showroom on April 19 and 20, directly on the final stretch of the Boston Marathon, letting tens of thousands of runners and spectators meet the robot for free, generating massive earned media at zero advertising cost.

Tesla has confirmed plans to expand its robotaxi service to seven cities in the first half of 2026, including Dallas, Houston, Phoenix, Miami, Orlando, Tampa, and Las Vegas, building on the unsupervised service already running in Austin. Musk has said he expects robotaxis to cover between a quarter and half of the United States by end of year. On the production side, Musk told shareholders that the Cybercab manufacturing process could eventually produce up to 5 million vehicles per year, targeting a cycle time of one unit every ten seconds. Scaling robotaxis to 10 million operational units over the next ten years is a key condition of his compensation package, alongside selling 20 million passenger vehicles.
As for the Cybercab’s price, Musk has said buyers will be able to purchase one for under $30,000, with an average operating cost around $0.20 per mile. Whether those numbers hold through full production remains to be seen.
