What is the difference between Active Steering and Active Comfort Drive on the BMW 7 Series?

I am considering purchasing a BMW 7 Series, but I am confused about the different steering options. Can someone explain the specific differences between Active Steering and Active Comfort Drive and how they affect the driving experience?

Active Steering adjusts the steering ratio depending on the speed, making it more responsive at low speeds and more stable at higher speeds. Active Comfort Drive, on the other hand, uses cameras and sensors to anticipate bumps and adjust the suspension accordingly, providing a smoother ride.
