   I do this is if there is a 'significant impact' on routing 
(subjective, I know).   Some of these garden dividers on roads in our 
area have been strategically placed so that all driveways have full 
access to either direction.

  On the other hand on a different road, a new set of garden dividers 
were placed so that dangerous left turns were blocked - I created dual 
carriageways for those because of the large change in the routing graph.
