Oh my God...We just found a GENIUS in u.... are u frm this planet, or specially landed on earth to raise this question.
We on PLANET EARTH understand that it is not 3% of the traffic, but a bus carrying 60 passengers equivalent to 30 Cars assuming 2 persons per car. Just after writing ur statement, u shud hv atleast thought abt wat u write. Plz understand to solve traffic problems, public transport has to improve & that is true in any part of the world & might be on your planet also. So, improving bus quality, speed, AC in buses is required to attract people use public transport like DELHI METRO.
If govt has to solve the problem by making new roads for increasing traffic (plz remember 1000 new vehicles are registered daily in Delhi), then 1 day govt would have to demolish ur house to make way for increasing the road width outside your house. Guys grow up....Think out of box....vaise dus vi ke paper de chuka hai kya tuu...
