As cars become increasingly “smart,” a critical new question arises: what kind of data do these vehicles collect about us, and who has access to it? Modern cars are no longer just transportation tools—they are advanced digital systems packed with sensors, connectivity, and computing power. They constantly collect, process, and transmit various types of data—about us, our driving behavior, our location, and even our entertainment preferences.
In this article, we will explore:
-
What kind of data smart cars collect
-
How this data is processed and transmitted
-
Who can access this data—and what laws regulate it
-
What risks and opportunities lie in this new data-driven mobility landscape
1. What Is a Smart Car?
A smart car is a vehicle equipped with sensors, internet connectivity, and an advanced onboard computer system. These systems can:
-
Collect data about the vehicle’s condition (e.g., engine, brakes, battery),
-
Analyze driving habits and road conditions,
-
Communicate with external systems (e.g., manufacturers, insurance companies, other vehicles).
Smart cars often fall under the broader categories of connected cars or even autonomous vehicles.
2. What Data Do Smart Cars Collect?
The data collected by smart vehicles can be grouped into four main categories:
2.1. Technical Data
-
Engine temperature, oil levels, battery voltage
-
Mileage, braking behavior, acceleration patterns
-
Diagnostic trouble codes (OBD)
2.2. Location and Navigation Data
-
GPS-based location tracking
-
Route planning history
-
Stop points, parking locations
2.3. User Preferences and Behavior
-
Volume settings, radio stations, playlists
-
Seat and climate control preferences
-
Driving style (e.g., aggressive braking, speeding)
2.4. Communication Data
-
Bluetooth phone pairings
-
Call logs, messages via infotainment
-
Online searches within the car’s system
3. How Is This Data Transmitted and Stored?
Data is usually transmitted via cloud-based systems. Modern vehicles are equipped with SIM cards or Wi-Fi, allowing real-time data transmission to:
-
The manufacturer’s servers (for diagnostics, software updates),
-
Authorized service centers (for maintenance records),
-
Third parties (e.g., insurers, mobile apps).
Storage typically occurs:
-
Locally within the vehicle’s memory,
-
Remotely in cloud-based infrastructure—often for extended periods.
4. Who Has Access to This Data?
This is one of the most important questions because location and driving data are highly sensitive. Potential data stakeholders include:
4.1. Car Manufacturers
Manufacturers often reserve access rights via terms of service agreements. They may use the data for:
-
Predictive maintenance,
-
Product development,
-
Customer service and marketing.
4.2. Dealerships and Service Centers
They use the data to offer maintenance recommendations or diagnostics.
4.3. Insurance Companies
Usage-based insurance (UBI) models rely on driving behavior data to determine premiums.
4.4. Mobile Apps and Service Providers
Car apps (e.g., Tesla, MyPeugeot, FordPass) allow users to access vehicle data—but also enable third-party access.
4.5. Government and Legal Authorities
Authorities may access vehicle data under legal mandates or court orders.
5. What Are Your Data Rights as a Driver?
In the European Union, the GDPR (General Data Protection Regulation) applies to personal data collected by vehicles. It ensures:
-
Right to information: You have the right to know what is collected.
-
Right of access: You can request a copy of your data.
-
Right to erasure: You can ask for data deletion if no legal basis exists.
-
Data portability: You can transfer your data to another provider.
Many users are unaware of what they consent to when installing car apps or accepting software updates.
6. Data Security Risks
Smart cars also introduce cybersecurity challenges alongside privacy concerns:
-
Remote hacking: If systems aren’t properly secured.
-
Data leaks: When third-party servers lack proper encryption.
-
Identity theft: Through unsecured Bluetooth or Wi-Fi connections.
Manufacturers are increasingly introducing safeguards such as two-factor authentication, encrypted data transfers, and user permission controls.
7. How to Control Your Vehicle Data
Here are some best practices to safeguard your automotive data:
-
Read the terms and conditions of all apps and platforms you connect to.
-
Disable data sharing features if they are optional.
-
Regularly update your vehicle software, as updates often fix privacy vulnerabilities.
-
Remove your phone’s pairing when selling the car.
8. Real-World Examples
-
Tesla logs almost everything, including footage from cameras and live data streams.
-
Volkswagen and BMW’s ConnectedDrive offer mobile apps for data monitoring.
-
Ford and GM models often support insurer-linked programs for behavior-based premium calculation.
9. The Future: Data-Driven Transportation
Data doesn’t only enhance the driving experience—it may become the foundation of fully autonomous vehicles. Real-time traffic optimization, urban planning, and safety features all depend on reliable vehicle data.
But one question remains central: Who owns the data—and how is it used?
Conclusion
Smart cars offer convenience, safety, and innovation—but also usher in a new era of privacy concerns. As users, we must take responsibility not just for how we drive, but for how our data drives the automotive industry. Understanding what’s collected, who accesses it, and how to control it is critical in this new connected world.
