Sir, we need an efficient transport system but the way it has been implemented in Pakistan, it is far from being efficient..rather it cannot recover even its own operational cost and it will remain so in the foreseeable future because we have not addressed the issue. People need to show discipline on the road. For this you need both very strict laws and good education. Metro, the way it has been constructed will never be able to replace the need for cars, motorbikes etc. Here in Sweden, people prefer metro over personal transport especially in the large cities like Stockholm because it not only reaches every part of the city but driving a car can be quite expensive as parking lots are limited and expensive and even there is a congestion tax between 08:00 to 18:00. This discourages people from taking car. Me & my wife both have our own cars and an SUV: three in total for a family of two but we use metros and bicycles more often than cars.
