Never is a long time, but I don't see self driving cars coping well when traffic is coming the wrong way down the street, let alone when cars are driving along the sidewalk
Yes, Cairo will probably have self-driving cars over a decade after New York has them. But that doesn't mean self-driving cards aren't a commercially viable product before they work in Cairo.
