"In the marketplace, the best wins. I am quite willing to fight in the market place... I urge all players to fight in the market," Tata said before he launched 'Nano', popularly known as the Rs one lakh car. He expressed anguish at the fact that all kinds of attack had been made on the project - from surface to behind.

Listing out controversies that had brewed regarding the car being a pressure on fossil fuel and not meeting emission and safety issues, he said, "I am somewhat sad that Indians are becoming the greatest critics... Why do we cut us down... Market will decide. Not you or us... If we succeed, we will have broken new ground."

Answering a wide range of queries from the controversies to the cost and the expectations during a free flowing discussion, Tata said though there was global visibility, but it was one of "disbelief and not of expectations."

What started off as a social issue to provide affordable safe transport as an alternate to two-wheelers, could become an attractive business with the Tata Motors working on variants to the economy car for upmarket buyers, he noted.
