How to Keep Your Car From Spying on You
New features on cars and phone apps can track where you go, when and how fast—among many other things. Here’s what to do about it.

Your car is watching you. What can you do to stop it?
Many vehicles today and their related phone apps are packed with safety and convenience features, including digital maps, navigation linked to GPS and the internet, remote starting and vehicle locaters to find your car in a crowded parking lot. Many also have microphones for voice control and some have cameras that detect who is driving to adjust things such as the seat.
But those features and others can have a dark side: Many can track where you go and when, how fast you drive and how hard you brake, where you park and spend time, even what music or podcasts you listen to. Such information can be a gold mine for marketers and insurers—and a target for hackers.
Privacy researchers say car buyers may not realise they agree to have such data collected by the automaker when they sign the papers for a new vehicle or use the carmaker’s phone app.
The Mozilla Foundation, a technology-focused nonprofit, examined the privacy practices of 25 car brands. Its conclusion: “These are the worst of any category we’ve reviewed,” says Jen Caltrider, director of the group’s Privacy Not Included program. Among its findings are that most carmakers collect personal information, give customers little control over it, and may sell or share it with others.
Privacy experts say they also are concerned about provisions in car-maker privacy policies that allow them to share driver information with law-enforcement authorities under certain circumstances—sometimes without a warrant.
On May 14, the Federal Trade Commission told vehicle makers that it was monitoring their actions regarding car data. “Cars are much like mobile phones when it comes to revealing consumers’ persistent, precise location,” the agency said in a blog post. It added that companies “do not have the free license to monetise people’s information beyond purposes needed to provide their requested product or service….”
The industry response
The car industry says that the combination of vehicle data monitoring, GPS and wireless communication—a field known as telematics—provides important features, some of them safety-related. Some systems can detect when you’ve been in an accident and call emergency services, or locate a car if it’s stolen. They can help you avoid a traffic jam or potential road hazards. Cars also can give you maintenance reminders, such as when a vehicle needs an oil change or new tires, and allow the carmaker to track the durability and function of certain components for future improvements.
A vehicle-industry trade group in 2014 issued voluntary guidelines for the collection and use of car data. The group, now called the Alliance for Automotive Innovation, says its members should give car owners and lessees choice in the “collection, use and sharing” of certain information and that this information should be collected “only as needed for legitimate business purposes.”
Some privacy groups, however, say the voluntary guidelines aren’t specific enough and aren’t always followed.
“It seems like an empty promise,” says Thorin Klosowski, a security and privacy expert with the nonprofit Electronic Frontier Foundation. “Car companies are becoming tech companies. Self-policing hasn’t been shown in other tech industries to be a reliable way for companies to operate.”
What is needed, according to these experts, is a federal privacy-protection law along the lines of the European Union’s General Data Protection Regulation. The car industry, for its part, also backs a federal privacy law , in part to have a nationwide standard as a number of states have adopted their own, differing laws.
Most carmakers issue their own lengthy privacy policies stating how they collect and disseminate car data. Some state that they can share or sell the information to third parties including marketers if the car owner agrees to it.
Among the six biggest sellers of vehicles in the U.S., Ford Motor says customers can turn off data and location sharing with the company. It says it “doesn’t sell any connected-vehicle data to brokers, period.” General Motors says it is “fostering trust through responsible data practices, enhanced user controls and clear benefits for customers.” Toyota says it gives customers “transparency and choice” in how vehicle data is collected and used and that they can “turn off all data transmission.”
Stellantis, owner of Chrysler, Dodge and Jeep, says any data it collects “is in accordance with applicable state privacy laws . Accordingly, Stellantis provides customers with a way to opt out of data collection.” Honda says it is “very clear about what we collect and how our owners can opt out” and “when we might share collected data with third parties.” Hyundai declined to comment and deferred to the Alliance for Automotive Innovation for a response.

Elon Musk is exploring a potential merger between Tesla and SpaceX, a deal that could reshape the future of AI, robotics, autonomous vehicles and space technology. With a combined valuation potentially reaching $3.5 trillion, the move could bring Musk’s vision of an interconnected technology ecosystem closer to reality, although a deal remains uncertain.

Elon Musk has engineered ties between Tesla TSLA 3.41%increase; up pointing triangle and SpaceX SPCX 7.79%increase; up pointing triangle that are hard to break, and now he wants to fuse them together permanently.
Musk has run both Tesla and SpaceX concurrently over the past two decades, using a schedule that dictated which days he spent focused on each business.
The companies have often shared resources and personnel, signaling their close ties. Last year, SpaceX looked into creating a spacesuit for Tesla’s humanoid robot Optimus, a person familiar with the matter said. Tesla last week showed off its new Roadster, a vehicle featuring SpaceX rocket thrusters that it hopes to soon bring to market.
And in recent months, Musk has repositioned both companies by expanding beyond their core operations toward a shared mission centered on artificial intelligence.
The world’s richest man on Tuesday signaled his interest in tying up SpaceX and Tesla, marking what would be the biggest corporate merger of all time. Because he serves as chief executive of SpaceX and Tesla, Musk said committees of independent directors at both companies are evaluating a possible deal, adding that a transaction might not come to fruition.
The committees will likely evaluate, with lawyers and bankers, how each company would fare in a potential deal and how a deal might best be structured. They then present their conclusions to their respective boards, who typically vote on whether to proceed.
“It’s an odd Kabuki dance where two groups of people are talking and I can’t be in the conversation,” Musk told SpaceX investors on Tuesday in response to an analyst’s question about a potential deal.
For Musk, the merger supports his vision of a world full of autonomous cars, humanoid robots and weekly rocket launches, as well as the data centers and satellites required to keep the whole thing running.
Some investors and analysts said they expect a transaction would be structured as an all-stock deal, with SpaceX potentially paying a modest premium for Tesla shares.
SpaceX, which has a market value of about $2 trillion, said it is seeing sharp growth in revenue across its businesses, which include operating data centers, launching rockets and operating satellite networks such as the internet service Starlink. Tesla is valued at about $1.5 trillion and is expanding its operations beyond its automotive and energy business. Shares in both companies traded higher following the news Tuesday.
Musk’s substantial ownership stakes in both companies, along with voting control at SpaceX, has enabled him to set the deal in motion. Analysts and investors said the deal will probably face regulatory scrutiny internationally, though some see Musk’s close relationship with the Trump administration as an asset to getting approval.
Blurred lines
The companies haven’t said which directors are on the special committees evaluating a potential deal. Several SpaceX and Tesla board members have either personal or business ties to Musk. And like Musk, venture capitalist Ira Ehrenpreis sits on both boards.
In a filing this week, Tesla outlined millions of dollars in business agreements with SpaceX and its subsidiaries last year, including $143 million in car sales to SpaceX, $3.3 million in advertising that it bought on the social-media platform X and $430 million in revenue from the sale of Megapack batteries for SpaceX’s data centers.
The companies also split the cost of resources including the use of Musk’s SpaceX jet and the bill for his personal security, which he runs through a private company.
Employees at both companies routinely move between companies to work on special projects, and some executives have dual roles, including Charles Kuehmann, vice president of materials engineering at both SpaceX and Tesla, and Ashok Elluswamy, the vice president of AI software at Tesla who runs a joint venture with SpaceX called Digital Optimus.
Over the years, Musk has launched new startups within his empire, including brain-implant company Neuralink, underground-tunnel developer the Boring Company and xAI, the AI startup that merged with SpaceX in February.
It is that AI business that Musk thinks can serve a market worth tens of trillions of dollars, justifying the need for a merger.
The business case goes like this: Tesla is developing robotaxis and robots, which it calls “physical AI.” SpaceX is working on the back end of physical AI: the data-center capacity and internet connection required for those robotaxis and robots to operate continuously.
“I don’t see what the value of Tesla is if it’s not merged with SpaceX,” said investment adviser Ross Gerber, a former Tesla bull turned critic invested in both companies. “If they don’t merge, the brains of everything that runs Tesla is owned by another company.”
On top of it all, both companies face constraints on the supply chains they need to make this world a reality, particularly when it comes to chips. To address this, Musk earlier this year announced a joint venture between Tesla, SpaceX and Intel to design and manufacture chips in Texas. “The most epic chip-building exercise by far,” he has said.
Musk at the wheel
For Musk, a merger would also solve two problems: demands on his attention and his lack of control at Tesla.
Tesla for years was Musk’s only public company, a status that came with greater scrutiny. There, Musk reports to a public board, as well as individual investors who make up around 30% of Tesla’s voting power, according to FactSet.
The question of Musk’s attention became a particular focus for investors and the board in recent years after he acquired Twitter in 2022 and launched xAI in 2023, and again in 2025 as he spent time in Washington, D.C., running the Department of Government Efficiency in the early months of President Trump’s second term.
As Tesla’s car business suffered in 2025, Musk threatened to take his AI ambitions outside the company if he wasn’t granted 25% voting control. Last November, Tesla shareholders approved a new pay package for Musk, which created a path for him to vastly expand his stake.
As of Sept. 30, Musk owned a roughly 20% stake in Tesla, according to the company’s proxy filing.
The SpaceX IPO gave Musk a different path. When SpaceX went public in June, the deal’s structure enabled him to have more than 80% voting power at the company—so much that he can’t be fired and decisions can’t be made without his support.
If SpaceX acquires Tesla, he will likely stay in control.
