<p>Streets can have unusual shaped like shown <a href="https://www.google.de/maps/@48.1353883,11.5717232,19z">here</a> in Munich. OSM
|
|
does not offer such data and therefore just renders an ordinary street contour like
|
|
shown <a href="https://www.openstreetmap.org/query?lat=48.13533&lon=11.57143">here</a>.
|
|
Because the data is probably not available this is a very hard challenge.</p>
