life in your own hands
"the K53 [South Africa's driving test] effectively requires an applicant to imagine that he is driving a live claymore mine under assault by guerrillas in bumper cars." - as described in the New York Times.
I have driven in South Africa. It was one of the single most terrifying experiences of my life. (I include being detained by Congolese border guards and jumping out of an airplane as things that were not nearly so scary.)
This explains a lot.
