Is your car spying on you? Here's how vehicles gather your data
CBC
When a Tesla Cybertruck exploded outside Trump International Hotel in Las Vegas on New Year's Day, authorities were quickly able to gather information, crediting Elon Musk and Tesla for sending them info about the car and its driver.
But for some, it's alarming to discover that kind of information is so readily available.
"Most carmakers are selling drivers' personal information. That's something that we know based on their privacy policies," Zoë MacDonald, a writer and researcher focussing on online privacy and digital rights, told Day 6 host Brent Bambury.
The Las Vegas Metropolitan Police Department said the Tesla CEO was able to provide key details about the truck's driver, who authorities believe died by self-inflicted gun wound at the scene, and its movement leading up to the destination.
With that data, they were able to determine that the explosives came from a device in the truck, not the vehicle itself.
"We have now confirmed that the explosion was caused by very large fireworks and/or a bomb carried in the bed of the rented Cybertruck and is unrelated to the vehicle itself," Musk wrote on X following the explosion.
To privacy experts, it's another example of how your personal information can be used in ways you may not be aware of. And while this kind of data can useful in an investigation, it's by no means the only way companies use the information.
"This is unfortunately not surprising that they have this data," said David Choffnes, executive director of the Cybersecurity and Privacy Institute at Northeastern University in Boston.
"When you see it all together and know that a company has that information and continues at any point in time to hand it over to law enforcement, then you start to be a little uncomfortable, even if — in this case — it was a good thing for society."
CBC News reached out to Tesla for comment but did not hear back before publication.
MacDonald says the privacy concerns are a byproduct of all the technology new cars come with these days, including microphones, cameras, and sensors. The app that often accompanies a new car is collecting your information, too, she says.
The former writer for the Mozilla Foundation worked on a report in 2023 that examined vehicle privacy policies. For that study, MacDonald sifted through privacy policies from auto manufacturers. And she says the findings were staggering.
"More and more modern cars are connected to the Internet, much like, you know, our computers and cell phones. And they're also a very sophisticated piece of technology," said MacDonald.
"What that means for your personal privacy, I'm not sure that that conversation has really caught up for one reason or another."
