It's BMW paranoia, even though the windows have anti-trap feature preventing them from closing if something gets in the way, BMW have deactivated it in NA in case it fails, and they end up getting sued for megabucks. They allow it in other countries (i.e. Europe) because the chances of getting sued for rediculously high punitive sums is much less (actually non-existent).
