Uber App - forced unsafe routes

The Uber app does not allow you to select routes based on safety. It also changed the original route without my authorisation - I caught an uber from the airport to the city and when I accepted the trip the route was via N2 and Buitengracht street. During the trip, the app changed the route to go via Strand street and the CBD, which is often not safe, and I could not change the route back - I had to beg the uber driver to stay on N2 and butiengracht street. This is really unsafe especially for foreigners visiting SA.
