<p>Possibly a router confusion with driving on the left... most
drive on the incorrect side of the road and get confused when
faced with the reverse. ??</p>
<p><br>
</p>
<p>Only thing I can see other than various offsets is the begining
of the 2 lane section heading north west .. happens a little
further along. <br>
</p>
<p><br>
</p>
<p>But everything in OSM looks ok for routing... <br>

<div style="direction:ltr">So on to the question, I suspect
it’s a router issue, but quite possibly something to do
with Menang Drive having tagging with bicycle=yes
cycleway:left=yes etc, but the Albany Highway ways not
having anything of the sort, not even lane quantity.</div>
<div style="direction:ltr"><br>
</div>
<div style="direction:ltr">Probably not relevant, but that
greater intersection looks like it’s been mapped with a
variety of aerial sources but without imagery offsets
being taken into account. The Maxar layer looks like the
most recent, and once I aligned that best I could (5.24,
-9.89), there are still a number of roads that are well
off the imagery.</div>
<div style="direction:ltr"><br>
</div>
<div style="direction:ltr">And the little bike diversions
for merging across aren’t mapped… but good riddance,
they’re definitely designed by someone who thinks that
it’s fine for cyclists on major highways who could be
doing 35 km/h to slam on the brakes to take a 90º turn to
cross a lane… ugh.</div>
