If `annotations=distance` or `annotations=duration,distance` is requested when running a MLD router, a `NotImplemented` error will be returned. |

|fallback_coordinate|`input` (default), or `snapped`| When using a `fallback_speed`, use the user-supplied coordinate (`input`), or the snapped location (`snapped`) for calculating distances.|
|scale_factor|`double > 0`| Use in conjunction with `annotations=durations`. Scales the table `duration` values by this number.|
Unlike other array encoded options, the length of `sources` and `destinations` can be **smaller or equal**
