I really think everyone exagerates the drivinghere. I have been to plenty of other places in the world (china, egypt, india, italy to give some examples) where traffic is much more challenging and scary than here. There is no denying you will a few unbelievable & highly illegal manouvers, but in a country of less than 1 million people, the traffic is fine. I have been driving here for 1 year now. There was a few weeks where I didn't have my own car and I went insane. If you already have your license, I suggest renting a car and driving straight away. You can drive on an international drivers license for the first few weeks until you organise your license. Renting a car ranges from about 1,600 (Brand new nissan TIDA) - 2000 (New Suzuki Swift) a month depending on what you want. But really your work should organise for you to get to and from work for the first few weeks til you sort yourself out.
