The Gautrain is fine, though pricey. The issue though is with the last-mile travel. How do you get from the train station to your house? Walk and you'll get mugged, esp. if you walk a regular route with expensive equipment on you, otherwise you take an Uber. The minibus taxes aren't roadworthy and drive like demons. So most people in Gauteng own a car with anti-hijack coatings on the window, or they Uber. In Cape Town there is no longer a working rail system because the trains were burned by the protesting populace. Even when the trains were running (with huge delays), you'd get pickpocketed on the train. You could never risk travelling at night if you had anything valuable on you.
