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.

At least for people who carry the APOE4 genetic variant, a juicy steak could keep the brain healthy.

Must even steak be politicised? The American Heart Association recently recommended eating more “plant-based” protein in a move to counter the Health and Human Services Department’s new guidelines calling for more red meat.
Few would argue that eating a Big Mac a day is good for you.
On the other hand, growing evidence, including a study last month in the Journal of the American Medical Association, suggests that eating more meat—particularly unprocessed red meat—can reduce the risk of Alzheimer’s in the quarter or so of people with a particular genetic predisposition.
The APOE4 gene variant is one of the biggest risk factors for Alzheimer’s.
You inherit one copy of the APOE gene from each parent. The most common variant is APOE3; the least is APOE2.
The latter carries a lower risk of Alzheimer’s, while the former is neutral. A quarter of people carry one copy of the APOE4 variant, and about 2% carry two.
APOE4 is more common among people with Northern European and African ancestry. In Europe the variant increases with latitude, and is present in as many as 27% of people in northern countries versus 4% in southern ones. God smiled on the Italians and Greeks.
For unknown reasons, the APOE4 variant increases the risk of Alzheimer’s far more for women than men.
Women’s risk multiplies roughly fourfold if they have one copy and tenfold if they have two. Men with a single copy show little if any higher risk, while those with two face four times the risk.
What makes APOE4 so pernicious? Scientists don’t know exactly, but the variant is also associated with higher cholesterol levels—even among thin people who eat healthily.
Scientists have found that cholesterol builds up in brain cells of APOE4 carriers, which can disrupt communications between neurons and generate amyloid plaque, an Alzheimer’s hallmark.
The Heart Association’s recommendation to eat less red meat may be sound advice for people with high cholesterol caused by indulgent diets.
But a diet high in red meat may be better for the brains of APOE4 carriers.
In the JAMA study, researchers at Sweden’s Karolinska Institute examined how diet, particularly meat consumption, affects dementia risk among seniors with the different APOE variants.
Higher consumption of meat, especially unprocessed red meat, was associated with significantly lower dementia risk for APOE4 carriers.
APOE4 carriers who consumed the most meat—the equivalent of 4.5 ounces a day—were no more likely to develop dementia than noncarriers. (
The study controlled for other variables that are known to affect Alzheimer’s risk including sex, age, physical activity, smoking, alcohol consumption and education.)
APOE4 carriers who ate the most unprocessed meat were at significantly lower risk of dying over the study’s 15-year period and had lower cholesterol than carriers who ate less. Go figure. Noncarriers, however, didn’tenjoy similar benefits from eating more red meat.
The study’s findings are consistent with two large U.K. studies.
One found that each additional 50 grams of red meat (equivalent to half a hamburger patty) that an APOE4 carrier consumed each day was associated with a 36% reduced risk of dementia.
The other found that older women who carried the APOE4 variant and consumed at least one serving a day of unprocessed red meat had a cognitive advantage over carriers who ate less than half a serving, and that this advantage was of roughly equal magnitude to the cognitive disadvantage observed among APOE4 carriers in general.
In all three studies, eating more red meat appeared to negate the increased genetic risk of APOE4.
Perhaps one reason men with the variant are at lower Alzheimer’s risk than women is that men eat more red meat.
These findings might cause chagrin to women who rag their husbands about ordering the rib-eye instead of the heart-healthy salmon.
But remember, the cognitive benefits of eating more red meat appear isolated to APOE4 carriers.
Nutrition is complicated, and categorical recommendations—other than perhaps to avoid nutritionally devoid foods—would best be avoided by governments and health bodies.
Readers can order an at-home test from any number of companies to screen for the APOE4 variant.
The Swedish researchers hypothesize that APOE4 carriers may be evolutionarily adapted to carnivorous diets, since the variant is believed to have emerged between one million and six million years ago during a “hypercarnivorous” period in human history.
The other two APOE variants originated more recently, during eras when humans ate more plants.
APOE4 carriers may absorb more nutrients from meat than plants, the researchers surmise. Vitamin B12—low levels have been associated with cognitive decline—isn’t naturally present in plant-based foods but is abundant in red meat.
Foods high in phytates (such as grains and beans) can interfere with absorption of zinc and iron (also high in red meat), which naturally declines with age. So maybe don’t chuck your steak yet.
