KDVT, from which I have been flying for over 30 years, has a runway separation of about 700 ft (I measure 695 ft in GE). I have often been on approach parallel to other traffic. I have also sometimes been on head on base with traffic for the other runway. It pays to adjust intercept angle and speed to achieve separation but that requires head outside to know where the traffic is. Tower usually keeps pilots informed of traffic for the other runway.
