Mate I'm on holiday in South Africa, the amount of invisible death bumps I've seen on 100km/h roads, without warning signs, which can only be taken at 5km/h, are insane. Our rental 4x4 lost 10 years of its suspension life during our 4 weeks trip, while I was lucky the bumps were marked on our navigation app so I could take them slow. And that's calculated without all the pothole terror. The roads here are almost as bad as roads in Belgium while the speed bumps are a hammer to your spine. If you want to start a good business here, open a tire and suspension shop.
