<p>You probably don't want to use the tracks directly to add roads
to OSM (you would only want to do this once in any case).
Definitely they could be useful for detecting which roads are
missing, and, if the available aerial imagery isn't good enough
for actually adding any missing roads. <br>

<p>Can you indicate where the city is?</p>
