Berg writes, "...many challenges remain. Transportation is a key problem in South Africa, where unsafe roads and unsafe drivers make car travel a hectic and dangerous prospect. And within its major cities, public transit has historically been absent. Ahead of the World Cup, cities like Johannesburg and Cape Town have developed bus rapid transit systems to transport people within the metropolis and to the soccer matches. And the first leg of a regional rail system has connected downtown Johannesburg with its international airport. Despite these projects (and many of the stadia) running far over budget and sparking local controversies, these are some of the long-term legacies South Africans are expected to enjoy after the World Cup is over."
