Does the IAS activate/make the steering more responsive at high speeds? I thought it's for slow speed maneuvering and has no effect at high speeds? What do magazine reviews say on this?
Mr. Magic is also saying that steering with IAS is more responsive?

Integral Active Steering.
A new, flowing driving feeling. More agility and stability in every situation. Rear wheels that help to turn up to a maximum of 2.5° degrees – a small movement with large effects.
In tight bends or when parking a car, Integral Active Steering makes maneuvering easier. Under 30 mph, the front and rear wheels steer in opposing directions to reduce the turning circle and ensure every bend is taken with direct precision.
Above 50 mph the front and rear wheels turn in the same direction to ensure an extremely comfortable and superior response on the road when changing lanes.
With Integral Active Steering, the driver and passengers in the BMW 5 Series Sedan experience a relaxed journey with increased comfort. Fast, flowing changes in direction, sharp bends, simple parking – enjoy steering that actively supports your driving pleasure.
