Ahh driving in Argentina?
I let my wife do the driving when we are over and that is in a small town, even as a native she quibbles at the thought of driving in BA not so much that she can't hold her own with the rest on the autopista but at the speed you have to go at, it's impossible to read the signposts!!! So we stick to taxis in BA ,far more enjoyable.
One observation of my mother in law's driving technique is that she just drives any way she wants and spends most of the time shouting "hijos da puta"
