This is going to be my attempt at starting a discussion regarding Tesla in Africa. We know Elon said that he wants a gigafactory at every continent so let's start the discussion now.
For Gigafactory I'd suggest the south of Egypt where the largest solar farm in the world is being constructed. The location is over 900 km "500ish miles from the Mediterranean however.
For an African market product I'd suggest a cybertruck-design compact 4Dr, preferably a crossover because that's all the rage these days. No paint, really tough body and cheap to manufacture.
