Narrative:
Feb/tue/89 at xa local. We were, again, being vectored for sfo quiet bridge approach. We were advised that our parallel traffic was 12 O'clock and about 2000' below us. When we spotted our traffic it was directly beneath the nose of the aircraft. This practice is unsafe. It raises tensions in the cockpit to a level that should only be attained during an emergency, not during a 'normal' procedure. The parallel 'quiet bridge' and 'tip toe' visual approachs should discontinue before there is a serious accident. In the very least, spacing between parallel traffic should be increased to a minimum of 3 miles.
