Now here comes the strawman. Where did I say Motorways are not important?
What, seriously

? Dimagh theek hai aap ka? One person pays 20 Rs and the government pays 40 Rs for it. Where is the revenue coming from??? I don't need to take any accounting course to know that revenue doesn't magically appear out of thin air.
Good god. Other parts of the world don't have metros with stops that are 10 km apart, neither do they have huge pillars in the middle of the road. What the hell makes you think that traffic reduced because of metros?? Whoever had a car before this metro would not get rid of it because of this metro. And whoever can afford to buy and travel in one would not spend his time being zaleel and khwaar in your metro bus.
And guess what? Because the stops are far apart and no one likes walking, the rickshaws and wagons are still really popular! No reduction in traffic but the congestion has increased thanks to the road area being halved.
It is not going to do anything if these thousands of people are going to get off and sit on a rickshaw to take them where they want to go. It might have reduced the road commute by a fraction of a percentage but it is simply not worth the money spent on it at this time, when it could have been spent on a lot more important things. You can argue all day long about how wonderful the Metro bus is but one thing is certain: the cost was not worth the benefit and the money was desperately needed elsewhere.
Some perspective here:

They can afford to make toilets while making metros simultaneously. If you don't believe me, just read this from UNDP:
Millennium Development Goal 1 | UNDP in India
And compare it to Pakistan:

While India was sending stuff to Mars and making Metros in Delhi, it was also working on its population's well being (i.e 'toilets').
Look, I would be all for the Metro bus and infrastructure development if it was feasible at this point in time. But there is no point arguing about it now that its done, so lets think about the future: we need good leadership and for that we need Democracy : so what about electoral reforms? Why is it that half the parliament is actually against Electronic Machines, even though the whole world (yes, India too) has them? Are they too expensive?
And what about electricity? For PMLN, micro hydel power generation is 'too expensive' but metro buses are not. Doesn't matter how you spin it, the truth is that when PMLN does something it is only for their own benefit.
