@HighVoltage I wish, if they are standard in sedans in your country, I might consider moving there! But serious answer, no it's far from standard and often an option in cars that have this feature. My Genesis sedan which was the top model trim didn't have split fold seats, only an armrest pass through. Also my friends and parents Merc S Classes don't have that feature either. Any owners of the 7 series, A8s or other top end sedans can chime in?
