As good a place as any to start - a few initial compare and contrast points - there will be more ...
There's no real concept of a regular vehicle inspection in SA - you'll see trucks belching out smoke in pretty much every colour of the rainbow. A garage is often a geezer on the side of the road with half a dozen exhausts in various states of disrepair and a oxyacetylene torch.
People don't seem too fussed about seatbelts either ... it's not unusual to see nearly a dozen people crammed into the back of a pickup (backie). All of them looking pretty chilled about the whole thing as well, unless it's cold when they're all wearing beanies and shivering.
The car is king - There are a couple of places in Joburg where you can park your car up and wander round the streets but in the great majority of places you drive everywhere. I live maybe half a k from the local garage and the gym but I wouldn't think about walking to either of those places. Most of the time you'll drive to the mall, park up and walk around in air conditioned comfort.
It's a country of massive contrasts - Sandton is one of the poshest suburbs - lots of hotels made out white marble, designer boutiques and fantastic restaurants. Yet maybe 5kms away is Alexandra - one of the biggest townships. There are more BMW's on the streets than you'll see in most British cities but the unemployment is beyond massive.
"It's pleasant all year round" - Maybe not the best way of putting it but it's true. Even in the depth of winter here it's equivalent to a crappy Spring day in the UK. At the minute the temperatures are ranging from the mid twenties to mid thirties - for someone coming from the UK where at this time of year you don't go out without a jacket it's fantastic.
South Africa has got eleven official languages (count 'em - Afrikaans, English, IsiNdebele, IsiXhosa, IsiZulu, Northern Sotho, Sesotho, Setswana, SiSwati, Tshivenda, Xitsonga) and a bunch of other
non-official ones. Yet the other week I was filling out a medical aid application form (there's no concept of nationally supplied healthcare here - you pay big bucks for it) and the choice of language was down to two - I'll let you guess which two.
Joburg is a really new place - I mean the city was only established 118 years ago. The place is generally built on a grid system (hence a hell of a lot of "1st Avenues" and the like). Everything is pretty new, albeit covered with a fine layer of brown Highveld dust. I used to live in Oxford in the UK - a pretty sizeable university town established a good eight hundred years before Joburg; in town there were two one screen cinemas, the nearest multiplex was a good half hour drive away. Within a ten minute drive of my place in Joburg there are four multiplexes.
Driving around Oxford was a complete nightmare - it was designed for horses not cars. Joburg is a lot more setup to handle traffic (although the morning commute is like putting your head in a fume cupboard for twenty minutes and relaxing to the soft rock classics on the radio - aaarghh).
