Street names as viewed from photos on street view cannot be copyrighted. (Copying the photo is not allowed though..) (As I understand it: Facts are not subject to copyright - a specific expression of the facts are) (Other interesting questions is whether filling the suburb on streets can be seen as copying the border around those streets in another map)
(Attribution requirements are for some specific cases - see act)
Copying Openstreetmap data won't be allowed either, as Waze's maps are under an incompatible license.
(Maps are classified as drawings in terms of ZA copyright legislation, which as protected as "artistic works" - The act is here: http://www.gpa.co.za/pdf/legislation/Co ... %20Act.pdf
- whether this is the relevant act is another question)
