Would you trade your privacy for a car? You might have that choice in the future

We’re all used to the tech business model that provides zero-dollar access to services in exchange for our data.

From the streaming music catalog of Spotify to the myriad services offered by Google, it’s an arrangement that seemingly benefits everyone: We get “free” stuff, while tech companies get access to a rich stream of information about their users that’s way more valuable to them than a one-off purchase fee.

This business model has become standard in the software world of ones and zeroes, but it hasn’t caught on in other walks of life. Just imagine the owner of a restaurant when you fail to present a credit card at the end of the meal, and instead offer to pay by listing facts about your eating habits. Would a car manufacturer be sufficiently interested in info to knock, say, 50 percent off the price of a new BMW should you promise to let them know where you drive it? Both of these examples seem fatuous at first glance. But why?

We get a bunch of “free” stuff, while tech companies get access to a rich stream of info.

A list of the world’s most valuable companies is dominated by tech giants, many of whom have proven that their habit of giving away access to services makes sense — and indeed, cents. It’s not limited to software, either. The price of smart speakers like the Amazon Echo and Google Home are bizarrely low, which is an odd strategy when Apple has shown what kinds of margins can be carved out on “must have” tech.

However, owners of the Echo reportedly spend around 10 percent more on Amazon after they buy the smart speaker than they did previously. The same is no doubt true for other “loss leaders” that give away underpriced hardware, knowing that it will give the companies something far more useful on the backend.

In a new book, a technologist for the Ford Motor Company argues that we may be entering a new era in the motor industry: one where the data that can be gathered from sensor-packed cars could offset the need to actually charge customers for new vehicles. A zero dollar car? According to John Ellis, it’s the direction things need to head.

“The model I present in the book works as follows,” Ellis, author of The Zero Dollar Car, told Digital Trends. “The original equipment manufacturer — Ford, for purposes of discussion — sells the vehicle data to a broker or to end companies. That is the monetization opportunity that everyone in the automotive industry keeps talking about. Based on what they are able to sell, they in turn use some of those funds to reduce the price of the vehicle. The more data they can sell, the more opportunity they get to reduce the price of the vehicle.”

A new source of revenue

According to Ellis, under this model car manufacturers could actually stand to make more money than they do charging a single purchase fee of, for instance, $40k. But who cares about your data? That changes by industry, but it’s likely to be the same mix of private and government groups that care about what you do online.

With a car, for example, it might be possible to sell the data from your traction control, headlights, wipers, and barometer to a group such as the National Oceanic and Atmospheric Administration (NOAA.)
With a car, it might be possible to sell the data from your traction control, headlights, wipers, and barometer to an agency such as the National Oceanic and Atmospheric Administration (NOAA). NOAA’s job is to predict future major weather incidents like storms and cyclones. Having thousands of weather data-gathering vehicles on the road would help, and it might actually be cheaper to shell out $3,000 for a lifetime of user data than funding a giant weather station.

On top of that $3,000, a car company could sell suspension-monitoring system data to the government organizations that maintain highways, or sell voice data from microphones in your car to Google to help train voice recognition systems or target you with better ads.

2017 marked the first year where IoT devices outnumbered the world’s human population.

While Ellis is predominantly focused on cars due to his job with Ford, the same model could be used for other things. 2017 marked the first year in which smart, internet-connected devices outnumbered the world’s human population. We have smart fridges, smart clothes, smart thermostats, smart watches, smart vacuums and heck, even smart toilets. The data that these gather from users is immensely valuable to companies. In a crowded marketplace, being able to offer an item for zero dollars would also immediately result in a massive boom in that product’s popularity.

“Now, I don’t necessarily believe you will [ever get an entire] home for zero dollars,” Ellis continued. “But a home where the mortgage payment is slightly less than it would normally be because of your selling data is definitely something we can envision.”

A thorny ethical dilemma

In some ways, this is a thought experiment. A bit like the Saw movies, where people are asked how much they would do to stay alive, the question here is how much data would you be willing to share to get things for less or even zero money?

We might be comfortable with sharing health data with our insurance company if we got a top-of-the-line “free” fitness tracker, or lower premiums. We might also be happy if we received money off our food bills if our smart toilet can monitor our excrement. We may be less happy if what we say in the comfort of our subsidized home is used to sell us ads.

“Consumers must realize that what they are considering free is in fact not free but rather zero dollars,” Ellis said. “Any of the mobile ecosystems that offer ‘free’ products are in fact offering zero dollar products. Free means nothing is exchanged in return. But all of these so-called ‘free’ products receive your data. And that data exchange is then a transfer of goods from each party. Second, the issue of ownership needs to be properly sorted out. If you purchase a product, what exactly are your rights versus the rights of others? This is not a philosophical question as it is at the heart of the zero-dollar economy.”

Ultimately, there are a whole lot of complexities to this. Would people with poor credit or low income levels feel obliged to surrender their privacy in a way that wealthier folks wouldn’t? Would it be possible to change your mind at 45 after selling a lifetime of your data to buy your first car at 18? Would data need to be anonymized in the same way if you were being paid a premium to access it?

It would certainly present a fascinating development that could help people in an age of increased automation of jobs and stagnating wages, though. How much data would you give up for a zero dollar lifestyle?

“Whenever I ask people that question, the answer hinges on how close the price gets to zero dollars,” Ellis said. “The closer you get to zero, the more willing customers are to say ‘yes’ to selling their privacy.”

Would you be among them?

Google and Cathay Pacific are using AI to tackle aviation’s overlooked climate problem
A third of aviation's climate impact comes from contrails most people never think about.
Aircraft, Flight, Transportation

Those wispy white lines trailing behind airplanes (called contrails) sure look harmless from the ground, but they're doing more damage to the climate than we realize.

As part of Operating Blue Skies, Google has partnered with Cathay Pacific, one of the major international airlines operating both passenger and cargo flights, to test and deploy AI-driven contrail mitigation technology across a region where air travel is growing faster than anywhere else: Asia Pacific.

The best tech of IFA 2026: a repairable laptop, liquid-cooled power bank, AI toothbrush, and more
From an AI toothbrush to a liquid-cooled battery, this is the best tech of IFA 2026
Best Of IFA 2026

IFA Berlin brought innovation from across the globe into one giant exhibition, and we got the chance to experience the new-gen "tech" firsthand. Walking through Messe Berlin, we saw a laptop designed to be repaired at home to a power bank with visible liquid coolant, an AI-powered toothbrush with a camera inside your mouth, and a robot vacuum carrying another.

The variety is what makes IFA one of the best tech shows. IFA 2026 runs from September 4 through 8, and we've spent our time in Berlin chasing down the products that caught our eyes. Some of these are clever ideas that may change how we use tech every day, while others solve a problem that I didn't realize existed.

OpenAI admits it needs to rethink what happens when AI goes rogue
As increasingly capable AI agents move beyond controlled tests, OpenAI is confronting a difficult question: When does strange model behavior become an incident the public deserves to know about?

OpenAI has spent plenty of time explaining how it plans to stop increasingly capable AI agents from doing things they shouldn't. Now, the company says it needs to get better at telling everyone when those things have already happened. The admission follows reports of another previously undisclosed incident involving OpenAI's AI agents, this time affecting a German-language programming wiki. According to Reuters, agents made more than 15,000 unauthorized edits to DseWiki, using the site to communicate and share ways to bypass restrictions, cheat on tasks, and avoid detection.

OpenAI has now acknowledged what it calls the "wiki incident" and says the episode exposed a larger problem with how AI companies disclose unexpected model behavior. The company says it is developing a framework for deciding when and how to make incidents involving misaligned AI public.
