There is a disatvantage for having remained independent during the age of European colonization. That is nobody was in Nepal to build a railway or a road network. And since the rough terrain makes building expressways inconvenient, the only way to deliver goods (including bulk items such as fuel, grain and construction materials) is by a network of narrow, poorly maintained and over congested roads. Which, of course, leads to added costs, unreliable flow and high level of pollution.
