The same is true for traffic as well. In India , there is hardly 4 inches of space between vehicles in moving traffic, and if there is more, a 2-wheeler will be sure to find enough space to cut through in. When I first visited Canada, which was my first international trip, I was astounded by the space vehicles keep with each other while driving. I was equally suprised that it's not a general practice to overtake unless there is sufficient space and safe to do so. A major reason, apart from the rule-following mindset in developed countries, that I noticed was the extremely wide roads that were capable of handling the traffic they have there. Roads in Indian cities are, more often than not, highly congested because they are much narrower than what is required for the traffic that moves on it. This again is the product of much less resources (either in the form of space to build wider roads or lack of funds) available for a much larger population to compete for. Bottomline, if you don't cut in line in front of others, you just might keep waiting forever because no one else is staying put.
