<p>This is basically a re-commit of <a class="issue-link js-issue-link" data-error-text="Failed to load issue title" data-id="310328954" data-permission-text="Issue title is private" data-url="https://github.com/openstreetmap/openstreetmap-website/issues/1805" href="https://github.com/openstreetmap/openstreetmap-website/pull/1805">#1805</a> , except I've removed the bit that separated out the <code>%{destinations}</code> template.</p>
<p>It now basically just fixes the ambiguous roundabout exit templating and refactors some of the code that builds the template name<br>
i.e. <a href="https://www.openstreetmap.org/directions?engine=osrm_car&route=53.7338%2C-1.5258%3B53.6832%2C-1.4999#map=13/53.7086/-1.5171" rel="nofollow">https://www.openstreetmap.org/directions?engine=osrm_car&route=53.7338%2C-1.5258%3B53.6832%2C-1.4999#map=13/53.7086/-1.5171</a></p>
<p>(See instructions 7-16 - its not clear that every other instruction is an instruction to <em>leave</em> the roundabout!)</p>
