What is necessary for an automated vehicle to operate with its auto-driving system engaged?

For an automated vehicle to operate effectively with its auto-driving system engaged, it is essential that the vehicle is capable of operating autonomously. This means that the vehicle should have the necessary hardware and software systems in place to navigate, make decisions, and respond to its environment without requiring input from a human driver. The auto-driving system encompasses various technologies, including sensors, cameras, and artificial intelligence, which allow the vehicle to understand and react to road conditions, traffic signals, and the behavior of other road users.

This capability is fundamental for the vehicle to be classified as an automated or self-driving vehicle, as its primary function is to perform driving tasks independently. While other choices address human presence, environmental conditions, and speed regulations, they do not define the core requirement for the vehicle's autonomous functionality. The emphasis on the vehicle's operational capability highlights the critical nature of technology in enabling safe and effective self-driving experiences.
