For other profiles such as cycling or driving, the "names" property of a RouteStep object will be the road or path leading to the next maneuver. However, when using the walking profile, the "names" property is always nil. This seems like a bug?
Along the same lines, the "instructions" property for RouteStep also doesn't include the next road/path when using the walking profile, while it does for other profiles.
