Sir: This is for all those geniuses who cross roads as if they own the road and think that the traffic will halt at sight of them. We are well aware of the deficiency of zebra crossings and pedestrian bridges in our country but it should not be neglected that crossing roads carelessly becomes very problematic for drivers. Driving in Pakistan is anything but easy. Drivers have a lot of things like crazy bikers, rickshaws, buses and people who drive like maniacs to worry about. Pedestrians add to their list of problems. On the other hand drivers should slow down at zebra crossings. ZAHABIA KHOZEMAKarachi
