How do the adaptive cruise control and active lane assist features in Audi A8 work?

I'm interested in learning more about the advanced driver assistance technologies, specifically adaptive cruise control and active lane assist, in the Audi A8. How do these features work together to enhance the driving experience?

The adaptive cruise control in the Audi A8 uses radar and camera sensors to maintain a safe following distance from the vehicle in front of you. Active lane assist works by using cameras to detect lane markings and gently steer the car back into the center of the lane if it detects the car drifting.

When using adaptive cruise control in the Audi A8, it's important to always stay alert and keep your hands on the steering wheel. The system is designed to assist with driving, but it's still up to the driver to maintain control of the vehicle.
