The automotive sector is going through a significant digital revolution. These days, cars serve as data centres on wheels and as a means of transportation. Connected cars produce and send enormous volumes of personal data, from voice assistants and GPS tracking to real-time diagnostics and driver behaviour monitoring. This innovation brings convenience and performance but raises questions about privacy and consumer data protection.
The challenge for automakers, mobility startups and suppliers are clear: protecting connected vehicle data while delivering next-gen digital services and staying compliant with evolving global privacy laws.
At Privacy Pillar, we work with forward-thinking automotive businesses to implement privacy-first strategies that build consumer trust, mitigate legal risk, and support long-term innovation.
What Is Connected Vehicle Data?
Connected vehicle data refers to the digital information collected and shared by vehicles through embedded sensors, telematics systems, apps, and vehicle-to-everything (V2X) communication platforms. This data can include:
- GPS location and route history
- Driving behaviour (speed, braking patterns, steering inputs)
- In-car voice commands and infotainment usage
- Biometric data (for personalized experiences)
- Maintenance alerts and engine diagnostics
As cars become increasingly autonomous and integrated with external systems, the scope of this data continues to grow – making automotive data privacy a critical business priority.
Why Protecting Vehicle Data Matters
A 2023 report by the Mozilla Foundation found that most major car brands collect more personal data than necessary, often without explicit user consent. Over 80% of the brands reviewed failed to meet basic privacy standards, raising red flags for regulators and consumers alike.
From a legal standpoint, regions such as the European Union (GDPR), California (CPRA), and now Canada (Bill C-27) are tightening rules around vehicle data collection and usage. But compliance alone isn’t enough. Consumer trust in connected technology is fragile—one breach or misuse can significantly damage brand equity.
Best Practices for Connected Vehicle Data Privacy
- Adopt Privacy by Design
Build privacy controls into the vehicle ecosystem from the ground up. This means embedding data minimization, consent management, and encryption into hardware, software, and services.
- Get Explicit, Informed Consent
Before collecting or sharing personal vehicle data, secure explicit consent from users. Provide clear and simple explanations about the information you are collecting and the reasons for doing so. Avoid buried legalese in manuals or apps.
- Implement Robust Data Security Measures
Protect in-transit and at-rest data with end-to-end encryption. Regularly audit telematics platforms and infotainment systems for vulnerabilities. Ensure role-based access control for internal teams and third-party service providers.
- Limit Third-Party Data Sharing
Many automotive systems share data with insurance companies, navigation providers, and mobile apps. Ensure all partners meet your privacy standards and have appropriate data processing agreements (DPAs).
- Offer Transparency and Data Portability
Drivers can view, update, or remove their data by GDPR and related regulations. This will give consumers a smooth method to control their preferences for vehicle data across apps and devices.
