If Tata car is going to add in polution and global warming, then very concept of American one car per person itself is a false capitalist concept and all americans should have followed like china or russia to stree only on public transport or use bycycle. Just because Americans are not getting credit of this they are commenting non sense. These same people are in fact copying our Neem, Basmati Rice and Curd rice and putting them as their petent to get more money and change the histry. These items are more than 1000 years Indian have ben using. If american have so much concern of polution, then they should stop production of arms and arms race in the world, distroy nuclear missiles, stop working as world policeman. Thumbs up to Tata Nano.
