I'm living in Egypt for 9 years now, but I drive in Cairo too! Egyptians drive crazy, they don't know any rules.
Since last year my children are going to school in Cairo, my eldest two will go to university this year. I am driving my daughter (now 12) to school, it is a short way: just from Mohandeseen to Zamalek. (2.5 km, sometimes it takes me 20 minutes!) Every other weekend we are going to Hurghada by car, I am always happy when I have left Cairo behind!

But I've heard that the traffic is much better since the new traffic law.
