I happen to drive to work today from the other side, because my family was spending the Sham El Neseem weekend out of the city.
Anyhow, I don't understand why people in Heliopolis and Nasr City(No offense intended for anyone there) don't acknowledge LANES. The concept isn't very confusing, you basically stay within the white lines and whenever you want to go to the other lane, you actually MAKE IT KNOWN. You don't however coerce the neighboring driver to flip suddenly to the other side, leading to the same thing to happen to the next and following driver, which eventually leads to a great wave of people changing lanes, nobody moving and multiple fender benders.

Sounds Familiar? Ever said it to anyone, or anyone saying to you?
I actually calculate when is the best time to use the blinkers. ONLY IN EGYPT!!!
