Dear Sandip. I understand your concern.Definately,with introduction of NANO car, no of car over the road will shoot up and we do not have enough infrastructure.All of us know that every human being born with some dream and every body expect in a certain living standard. There are millions of middle class who really wish for car but cant coz of high price.TATA want to make middle call drean of car in reality.what will happen if people live short life becoz pollution created by car.Nothing.As told for millions it is dream to have car and there no other bad thing than killing our dream and feelings.Regarding infrastucture GOV has to think not TATA.Every thing have certain advantage and disadvantage.
