I tend to be of the opinion that BMW sets their interval at 15k simply because they are footing the bill while the car is under warranty and as a function of 'planned obsolescence'.
After 100k miles/6 years, they want you to buy a new car, not keep maintaining the one you're in. Perhaps those 15k intervals produce just enough wear and tear to cause more expensive maintenance issues outside of the warranty period, driving people to avoid keeping the older car.
