The Tato Nano Car will bring affordable transportation to many who can not afford a car. This has many environmentalists in an uproar. The mistake we make is that we always try to use economics as a means of control. All this does is force hardship upon those who already have enough difficulties in life.
Certainly the Tato Nano is more earth-friendly than an SUV. The pollution problem could be solved in a very-short time by implementing a speed limit of 30 miles per hour. But that will never be accepted because that will force EVERYONE to change their lifestyle and not just those who can barely afford a Tato Nano.;)
