I will be forcing her to drive the car so she can get use to driving here. Then she will feel more comfortable to drive on her own
In general how do people drive in ZN?
Cautiously, which in itself is sometimes a problem. Its a lot slower and relaxed then SA and people are generally friendly, give space and do not get road rage if you take to long. Employers also understand traffic sometimes exist and is lenient in leaving early or arriving late if there are problems on the roads.
The rules of the road are catered for cyclist and pedestrians. (see photo below of a general pedestrian crossing). This becomes a stop street if a pedestrian crosses, and some don't even look before they cross and will just walk. I have seen some close calls but in general, cars will stop.
One thing that I am still trying to get used to are circles, or roundabouts as they are known here. There is no gap, or who enters the roundabout first, you yield to the right and wait till ALL the cars have gone. Then they also indicate twice ...

One to enter the roundabout and again to where they want to exit, so cars that go straight and we not use to indicate will enter the roundabout and indicate left but not exit left but carry on straight, or if they want to turn right (3rd exit) they will indicate right as they enter and then indicate left just before they exit at the 3rd exit.
Something to get use it and does cause confusion from time to time as its a 50/50 chance if someone is going to indicate or not....
Then the other problem is space.... Here street parking is very much acceptable and often suburban streets will become 1 car wide as cars are parked on both sides of the roads. Some area's it becomes very tight so caution and knowing the area is crucial.
