Autonomous vehicles are intelligent cars that perceive their surroundings using in-vehicle sensing systems, plan driving routes automatically, and control the vehicle to reach a predetermined destination. To achieve this, they require the collection of vast amounts of data, which is then analyzed to handle potential accidents or obstacles on the road. But what exactly does this data mean for the car and its owner? Let's explore this with insights from automotive electronics experts.
A recent article in *The New York Times* highlighted concerns about how much personal data is collected by vehicles. According to Intel CEO Brian Krzanich, a driverless car can generate up to 4,000 gigabytes of data per day, while Barclays’ Brain Johnson claimed that just one minute of driving could produce 100GB of data. These numbers may seem overwhelming, but it’s important to understand the difference between traditional and autonomous vehicles.
Currently, most standard vehicles collect minimal data, store very little, and transmit even less. However, as more cars become equipped with advanced Sensors, cameras, and connectivity features, the amount of data being gathered is growing rapidly. Some vehicles now come with emergency data loggers that record critical information during accidents, such as location, speed, and vehicle parameters. For example, General Motors' OnStar system automatically sends an emergency call with crash details when an accident occurs.
While these features can be beneficial, they also raise privacy concerns. In the past, some individuals have used such systems to track their partners, and law enforcement has even used them to locate suspects after incidents like the Boston Marathon bombing. When smartphones connect to a car, private data such as contacts, messages, and location history might also be collected.
Not all automakers prioritize user privacy when collecting data. Navigation systems may log where you've been, and if your car has wireless capabilities, your travel patterns could be sent to third-party services. Vehicle performance data might also be collected throughout the ownership lifecycle—whether you buy, lease, or use the car—and you may have little control over how it's used.
However, companies like Otonomo and IBM are working with automakers to improve data practices. In the future, users may have more control over what data is shared, similar to how we manage app permissions on our phones.
Unlike regular cars, autonomous vehicles process massive amounts of real-time data, though only a small portion is transmitted wirelessly. Most data is stored for later analysis. OEMs are still figuring out how to balance data collection and transmission, as the full value of in-vehicle data is not yet fully realized.
Some manufacturers, like General Motors, are exploring ways to monetize data by selling access to Wi-Fi or sharing it with service providers. Meanwhile, vehicle performance data—such as engine health, tire pressure, or brake wear—can be useful for improving product quality and preventing issues before they occur.
By focusing on this kind of data, automakers can address problems like sudden acceleration, airbag malfunctions, or engine fires early, reducing accidents and recall costs. This proactive approach could also help avoid regulatory scrutiny.
In summary, while data collection in cars raises privacy questions, the main goal isn’t to invade your personal space—it’s to better understand and improve the performance of your vehicle. As technology evolves, so will the way data is handled, ensuring a safer and smarter driving experience for everyone.
