[OSM-talk] Removing redundant routing instructions

In the UK (particularly in rural areas) it is common to find a road that
turns 90 degrees to the left or right without a junction (that is the road
just continues and white lines mark it as such). Meanwhile another road may
come in from the other side with a 'give way' style junction.
Although the road continues round the bend "SatNav" systems often think it
is a junction and tell you to "turn right/left in 100 yards/meters".
I wonder whether it is possible to indicate this in OpenStreetMap so that
routing engines can omit this redundant instruction.
== Example picture ==
In the example Oban Road  turns to the right to become the northern
section of Sydnall Road. All main routers tell you to turn right. In my
opinion this is a redundant instruction (or could be better worded). I've
tried to add extra nodes so that the road naturally bends but the main
routing engines still tell you to "turn".
== Question ==
Could we benefit from a new route relation? For example a "route_continues"
relation? Would others find this useful?
