I hired a car in Johannesburg for 7 days. First stop Bloemfontein where I visited the Boer War Museum. Distance 395 km and it took 4 hours, mainly good 4 lane Toll road all the way, 120 kph speed limit with one mobile speed camera which Google warned me about. 3 toll stops R25.50, R84.50 and R72.50 about US$10 which is expensive for this part of the world as a result there was not much traffic. The countryside was flat with Shanty towns of tin shacks dotted along the way.
I stopped here to visit the Boer War Museum which is very good. The town has a 30% white and 56% black population and is quite civilised with large pot holes which are a feature of South African roads hahaha.
