Some of the false positives were freeway links that are shown as
disused=yes.  They were on freeways that abruptly ended.   Adding in sql
code to omit disused=yes would catch some.  Most of the other false
positives were at connections between motorway links and the main freeway.
  Not sure I understand why.  I couldn't see a pattern for those.  Only one
possibility comes to mind - the nodes were connected after you grabbed the
data.
