 From the wiki Example:

"If you are heading north on the A56 and want to continue on the A56 
then you need to turn off the main carriageway or you end up on the 
A682. Currently any routing software based on OSM data will not tell you 
to make a left turn"

Excuse my ignorance, but if your destination is Haslingden, why can't 
the routing software send you left at that junction? What makes it 
different to any other turning?
