It’s not just your phone — cars can collect a lot of your personal data, too: Many of the latest car models allow manufacturers to pull hundreds of data points from these cars when they’re on the road, including where you drive it, Christina Rogers writes for the Wall Street Journal. “With mns of cars rolling off dealer lots with built-in connectivity, auto companies are gaining access to unprecedented amounts of real-time data that allow them to track everything from where a car is located to how hard it is braking and whether or not the windshield wipers are on.”

The data is meant to be used to improve car models, but there are natural privacy concerns that come with the availability of so much personal data. Some manufacturers are putting the data towards creating new and personalized service, such as apps, but others are thinking of monetizing the data by “selling it to mapping firms looking to provide more accurate traffic information.”
