Final answer:
Connected cars are categorized under Industrial IoT, as they involve advanced connectivity and automation that goes beyond personal use, impacting broader industrial systems and services.
Step-by-step explanation:
The category used in the context of connected cars is typically Industrial IoT (Internet of Things). In the realm of IoT, connected cars would fall under Industrial IoT because they involve the integration of complex systems and a high level of automation and connectivity that serve functions beyond personal convenience, contributing to smarter transportation networks and urban planning. Although connected cars can be personal vehicles, the technology, and infrastructure they interact with align them closer to Industrial IoT due to the scale and impact on industries and public services.
