Digging into Safari planning and have studied numerous websites and ordered several books on Amazon including maps. So, wondering if I could self drive to various parks/camps and then go on drives from there?

In all my travels, I always have anxiety about what driving is like in a foreign country, usually unfounded in modern times as soon as we land and get the car. I've done pretty well in most countries. But I've never been to Africa.

So a few questions:

1) Main roads and highways from Johannesburg to Kruger and into Botswana --- what do they look like (divided highways, good repair, marked exits)?

2) What side of the road do they drive on?

3) Driver behavior -- generally normal? maintain lanes, turn signals, brake lights, etc.
