Roads are generally of a high quality in ZA, however many drivers take unnecessary risks like overtaking on blind corners.
Also, speed limits are usually ignored on the open roads, with speeds of up to 160km not uncommon.
An added worry are the number of people walking along the side of the highways. Don't expect it to be like North America. There are no vehicle-only roads, they are shared with pedestrians.

Latitudes.
For my part, I travel not to go anywhere, but to go. I travel for travel’s sake. The great affair is to move; to feel the needs and hitches of our life more nearly; to come down off this feather-bed of civilisation, and find the globe granite underfoot and strewn with cutting flints.
Robert Louis Stevenson (1850–1894)
