What is the purpose of the Active Lane Assist feature in the Audi A2?

I was looking at buying an Audi A2 and noticed it has an Active Lane Assist feature. Can someone explain what this feature does and if it is worth the extra cost?

The Active Lane Assist feature in the Audi A2 uses cameras and sensors to detect lane markings and helps keep your vehicle in the designated lane. It can also provide gentle steering assistance to keep the car centered in the lane. In my experience, it is definitely worth the extra cost for added safety and convenience while driving.

I purchased an Audi A2 with the Active Lane Assist feature and it has been a game changer. It takes the stress out of long drives by helping to reduce driver fatigue. Highly recommend it.

As someone who commutes on highways frequently, the Active Lane Assist feature in the Audi A2 has been a lifesaver. It alerts you if you start to drift out of your lane and can even steer you back into the lane if necessary. Definitely a must-have for highway driving.
