How Much Data Does Your Car Actually Collect?

Article Written By: Safaa Ali and Christina Timoshkov Introduction

Most people know that their phones collect personal information, but fewer realize that their cars can do the same. Every time you drive, your vehicle may collect information about your location, driving habits, and even activity inside the vehicle. As cars become more connected and advanced, data collection has become a normal part of driving. But what exactly is your car collecting, where does that information go, and how much should you worry about your privacy?

How Do Cars Collect Your Personal Data?

Even if you don’t realize it, today’s vehicles have computers and sensors built in. When you connect your phone or another device to your car’s through Bluetooth, the vehicle can access certain information from that connected device. This allows the car’s computer system to communicate with your phone and potentially store information such as contacts, call history, and other connected-device data.

Newer vehicles can collect even more information through built-in navigation systems and apps. These systems may remember frequently visited locations, preferred routes, and other driving habits. This information can then be used to provide personalized recommendations, such as nearby stores or gas stations. Although these features could be handy, they collect personal data that the driver may not realize. These systems can collect information from both the vehicle itself and device connected to it. This raises an important question: what types of information can modern vehicles collect?

Types of Data Collected

Vehicles can collect much more than location history, connected-device information, and contact details. Other information may include account details, call history, and information about streaming services accessed through the vehicle. Vehicles also collect information about how the driver operates the car. This can include speeding patterns, seatbelt usage, and braking behavior. Beyond monitoring driver behavior, modern vehicles may collect environmental data as well, including information regarding road conditions, traffic patterns, traffic signs, and weather conditions.

Data Sharing and Storage

Collecting data is only the first step. Where does that information actually go once your car grabs it? Some stays put, stored directly in the vehicle, while other bits get shipped off to the manufacturer or dumped onto company servers. Connected features, such as navigation systems, mobile apps, and emergency services, depend heavily on this flow to function.

Privacy policies dictate the rest. Depending on the company, your data might slip into the hands of third-party providers or business partners. A normal drive doesn’t guarantee your information stays inside the car.

Concerns and Risks

While car data may be useful, it also raises privacy and security issues; for instance, location information could reveal the places you visit regularly or your daily routines, and driving data could indicate how fast you drive, how frequently you brake, or the way in which you use various features of your vehicle. There is also the possibility of a data breach. Just as data kept by websites and apps might be made available if the systems of these companies are attacked, so too could the data held by car companies if their systems are compromised. The greater amount of information a connected car gathers and stores, the more crucial it is for the companies to protect it.

How To Stay Safe

You do not have to stop using every connected feature in your car to protect your privacy. Start by checking the privacy settings in your vehicles and any apps connected to it. Turn off data collection or sharing options you do not need, especially features that involve location or personalized services.

It is also a good idea to read through the manufacturer’s privacy settings, keep your car’s software updated, and remove personal information before selling or returning a vehicle. When connecting your phone, pay attention to what permissions the car requests instead of automatically allowing everything.

Conclusion

In today’s world, cars are becoming like computers on wheels, following with all the data. Information regarding your location and your typical vehicle usage can make features fairly more convenient, yet still raising questions regarding personal privacy.

Cars collecting data isn’t necessarily something to be scared about, but rather something to be aware of. Understanding what your car collects can help you interpret what information you’re truly comfortable in sharing. So the next time you consider where you can share your information, your phone might not be the only place worth checking.
