We need few international airports in Nepal, unfortunately we hardly managing one. One reason people are crowded in Kathmandu because its only place to fly abroad and land incoming tourists. All cities of Nepal are not planned for 50/100 years. We try to control the situation (not solve) once problem started (for example demolish buildings when traffic increased). Cyclist, motor bike rider and pedestrians have almost zero rights than truck, bus and car drivers. They kill pedestrian if he/she is just injured (to minimize liability). Technology and development do more harm than benefits when public are not enough civilized. And also Nepalese people feel shame to ride bicycle when they can afford to drive foreign cars with foreign imported highly priced kerosene mixed petrol/gas.
