I live in Centurion, 4.5 kms away from where I work. About 10-15 minute drive. One reason I might never buy a house one day is because of the prospect of staying very far from work. If I buy a house in Centurion and then get offered a job in Joburg, I'd prefer moving closer to work than travelling long distances. It's easier to rent than to buy a house in that sense.
