I was reading this thread out of interest because with my new phone I can finally use the latest waze instead of the old symbian version
, so I've started exploring the 'Stops' function. When I noticed the name 'strandloper' I thought: "Ah, another South African". Then I looked at the map again and realized that I live almost in the centre of that map, near where the 3 routes converge!
I have found that routing to my house from the Gants area (in the general area of A) it sometimes suggests the red route. If I try again it will sometimes change to a route similar to the green route. I agree that the red route will normally take longer, but since the turn from the N2 onto Victoria St (where Green and Red diverge) sometimes takes a long time, and there are more traffic lights and traffic on the green route, the difference in route times may not be as significant as one might think. Possibly waze still needs to get more speed info from wazers driving those roads to be more accurate.
But all of this does not explain why you get the red route only when selecting a Stop. I have just tested with my phone and can confirm the behaviour you've reported. (I have 'Fastest' selected). I guess it must be the issue mentioned in the link TonyG-UK posted. So I guess you should keep trying the Stops function and see if it comes right again.
