I don't disagree with your comment per se, but I think you missed the point of Nursie's comment.
sanman2 said "India's poor" are "turning their noses up" at the Nano.
However, 32.7% of Indians live in poverty. Because of this, Nursie rightly pointed out that "India's poor" probably have bigger concerns than which car to buy.
If sanman2 had said "members of India's lower middle class are already turning their noses up at the Nano" there would be no argument here.
I have been to India several times in the last 10 years and seen huge numbers of people sleeping on the streets and in shanty towns.
