There was a map issue reported here https://world.waze.com/editor/?lon=28.08173&lat=-26.16492&zoom=7&layers=BTTFFTTTTTTTTTTTTTTTTTTFT&segments=102835990 saying that Waze routed incorrectly.
The issue is that the gated road was closed. As you can see in Street View the gate is sometimes open : https://www.google.co.za/maps/preview#!q=Louis+Botha+Avenue%2C+Johannesburg%2C+Gauteng&data=!1m8!1m3!1d3!2d28.081231!3d-26.164853!2m2!1f107.55!2f90!4f75!2m4!1e1!2m2!1sOm4cr5msz05tPVSgNBEWqQ!2e0!4m10!1m9!4m8!1m3!1d136815!2d28.0400245!3d-26.1715215!3m2!1i1639!2i917!4f13.1&fid=5
How should we deal with this?
