1. You might hear South Africans speaking about robots – it's what they call traffic lights.
2. A distinctly South African phenomenon is the ‘car guard’, a self-employed person who will offer to watch your car for a small fee. You should carry small change for this, but bear in mind that the system is completely unregulated, so use your discretion.

Your car hire company will tell you what to do in the event of a breakdown.
