Hi, I understand where you are coming from. Have the same fears myself. Especially with the speed, beeping of horns, not using indicators, very little road courtesy, people crossing without looking, children stunting on roads, drivers weaving in and out and roundabouts are nightmares to me here. Also coming from UK, the road directions here took some getting used to. I started out driving in my neighbourhood during daytime (when no one else is out). Next I set out the route I will be taking, the turns involved, what I should look out for and what I can expect to encounter on that drive. Then went on short runs to nearby shops during non busy traffic times. After that, did the big roundabouts and big roads during non traffic times. Still do most of my driving during lower traffic times actually as it is easier on my nerves and teeth. You can try that just to gain confidence in handling the car, roads and driving situation here. Good luck.
