why is Adaptive Drive so rare?

The OP is in Chicago, so it is safe to say he/she is referring to US market vehicles. When an X5 here has the "sport suspension delete" option, it is referring to a vehicle with Sport Activity Package, but without Adaptive Drive. There was a time that this is how it had to be ordered. It does seem that BMW has made an effort to make this more simple by makng Adaptive Drive as a stand-alone option on all models, however this was not always the case.

Is the "sport suspension" on the M Sport Package without Adaptive Drive truly different than other current X5s? I doubt it, but if you have an indication otherwise, would like to know for sure.
