Smart City Focus: Smart city initiatives mainly address infrastructure, environmental monitoring, and optimization of public services.

Ride-sharing Context: While self-driving technology could contribute to future smart city transportation, it's primarily a private-sector innovation, not a core municipal service like the other options.

Typical Smart City Applications:

Wi-Fi: Provides public internet access, enabling data collection

Pollution Monitoring: Tracks air/water quality for environmental management.

Demand-based Tolling: Adjusts pricing for traffic management.
