Weird...I have never had such a complaint in the last 5 years of hauling around people with my x5's. Neither had sport package, both on 18s. I do not drive particularly docile either.

My mother actually feels the x5 is very soothing on long trips, and she was coming out of a lexus rx300! I think its the ergonomic seat, and the windows and roof... shes somewhat claustrophobic. Furthermore my sister use to get motion sickness on trains etc, and she has never had an issue in my truck.
