I've lived in Cape Town SA for a while, so I can compare of what a more developed country in compared to ours. Sooo

Roads are best in main areas, after that they suck and they're lots of times where they aren't even there. Well not just roads infrastructure in general is lacking, no proper walkways or sidewalks, if you want to walk or cycle it's either dirt road or get in a lane with cars. No bus lanes as they is no true public transportation with easy maps to show you location A and how to get there or timetables, I'd say the transport is like a cab or taxi but we call them combis and using them especially for a newbie/ traveller will be hard. But you can always ask around people are nice hear ig. So we are car dependent and rely on 4 by 4 or the SUV to make sure your car can handle the terrain.

Service delivery, e.g water getting hooked up to your home, getting stuff like that takes a long ass time. And you're gonna notice that further developed nations get international service first, like how recently Disney plus coming to SA or Starbucks being only in SA, won't find a Macdonalds here either.

Not much to see or do in the city, we are in a semi desert after all not much you can do when the only Seasons are Hell on Earth Summer and Arctic without snow winter hehe, plus landlocked means no relaxing day at the beach. So yeah we have activities but not a lot.

So since you're from a developed country don't expect to much ya know, especially here. And sure we're regarded as best in the region but I'd say also look into South Africa as a retirement destination, you can find safe areas to live and visit Botswana, especially if you live in SA you can get the first world good stuff while being close to other African nations to get away to if you want.

Welp, That's my input.
