All these cars are pies in the sky. Buying these cars is just like marrying a world beauty, for others to gawk at. Serves no purpose in our daily lives.
We have to go for hybrids and similar energy efficient cars to cut the emission levels. Honda is already investing in a hybrid facility in China, while our requirement is more urgent. Hybrids can have more efficiency in city driving as the batteries are charged on breaking (we have more of that in our cities) and so lat us work towards that, than getting over excited on these white elephants.
