Hi Wigwam,
Having hired cars many times over the years, both in the Highveld and the Cape, I suspect EVs will be a hard sell in SA and Africa as a whole. For commuting to the office/school run in urban areas or as a second car, perhaps, but once away from the cities, range anxiety as we know it would be greatly increased by thoughts of threats to personal safety. Magnificent country, but a constant sense of unease, sadly.
