<div dir="auto">I, for one, consider not including bicycle lanes to be a harmful shortcoming. It tells you nothing about where, how many or what turn restrictions apply to the bicycle lanes, all because bicycle lanes don't count because reasons. It also means lane guidance where bicycle lanes exist will automatically be off by a lane and makes it useless for cyclists, who need lane information more given relative difficulty changing lanes. This is something that desperately needs to change. </div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Jul 30, 2019, 06:27 Volker Schmidt <<a href="mailto:voschix@gmail.com">voschix@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div>Comments on the <a href="https://wiki.openstreetmap.org/wiki/Key:lanes" target="_blank" rel="noreferrer">Key:lanes</a> page</div><div><br></div><div>1) Heading "Narrow roads" <br></div><div>The pageit proposes:</div><div>
