Why do I find that confusing?
Currently in general the directions ignore corners even if there are
roads going off those corners. The complaint is about 'extra' directions
where the corner is actually the main road and the straight on branch is
the turning. If the directions remain silent one would in some
conditions get confused so the safe thing to do is announce both?
The correct wording of the the directions should be perhaps 'road bares
right' and 'go straight on' rather than 'turn right' but that does need
the perhaps missing "through_route" information? As I said, the
inclusion of road names in OSMAND while useful at times does get
similarly annoying when a 'continue on Axxx' would suffice. In this case
the road id provides the "through_route" information ... one remains on
the same road ... and the straight on road has a different one which may
just be 'minor road'.
