Survivability of occupants in a car built like that, even in lower speed accidents would be terribly low. I cut people out of cars (I'm an FF) and I can tell you NA built cars are some of the best physically built in the world for passenger survivability. I've seen people walk away from accidents that when you arrived on scene and just looked at it you would swear you're just going to be recovering bodies. Its a testimony to our safety and build standards - that doesn't get talked about a lot, but manufacturers should talk about that.
Someone mentioned we should lower our standards to enable more car ownership. Thats the most assanine thing I have ever heard! Roll back 30 years of evolution of research and development of safer and safer cars? I still send the wife and kids to school in a '98 Dodge Durango. I don't care about mileage for the 4km, I care about safety, four wheel drive and being able to nav the snow in bad weather. People generally don't die in Durango accidents, at least on the inside of the car (outside is another story).
This car comes from India where, I mean no disrespect, but life is cheap by their standards. People die every day from accidents and illnesses that we don't consider acceptable in this part of the world. That car is an evolutionary step for them, but it should stay in India. You want a reasonably safe car with that kind of footprint buy a Smart Fortwo. These cars have an excellent passenger cage system and for its size and type is far safer than a Nano.
