Why do you worry what americans are thinking /joking about Nano.
The Nano is designed keeping indian middle class family in mind. If this car's on road performance is meeting the min reqd expectations it will be a hit, lakhs & lakhs of them will be consumed by indians.
Let us be proud that an indian company has showed the world what a japanease or an american company had thought as "not possible"
This has changed the perception of the world about indian management / manufacturing epertise. May be some of the so called multinational companies are feeling insecure about the "New order" emerging from India.
Heart felt congratulations to Mr. Tata & his team. You have made us all indians proud.
