A friend and I have booked a hotel in Jo'burg during the world cup, but we're on a tight schedule and would like to visit Cape Town, if even for a couple of days (Leaving Jo'burg on June 13 and have to be at the city of Polokwane on June 17). I imagine train and bus are too exhausting, and I'm also worried about plane safety and price of air travel in south africa.
SthAf highways are good but the locals have no respect for speed limits!
It's a very long drive from Jo'burg to Cape Town, so don't try to do it all in one hit - fatigue will get you!
Watch out for the animals which wander onto the roads, especially at dusk and sunrise (some of them can be quite big!). Many South Africans (who cannot afford a car) also walk on the roadsides... try not to hit anyone.
A ggod way to see the country (I did the garden Route; from Cape Town to Pt Elizabeth, 800 km with a couple of nights in Pletenberg Bay) but time consuming. almost 7 years ago
