Ignorance + No Facts + wrong attitude towards citizens of other country = people like you.
Tata is one of the world's most trusted brand ahead of Microsoft, Google, Intel. I could say the same for these american companies, as you said for Tata. Regarding Nano, its one of the most safest car, certified by tens of agencies and reviewed worldwide.
Tata Motors will offer a version of the Nano with these safety-features, including an airbag system in its electric version[citation needed]. The Nano has an all sheet-metal body made from Japanese and Korean steel, with safety features such as crumple zones, intrusion-resistant doors, seat-belts, strong seats and anchorages, and the rear tailgate glass bonded to the body. Tires are tubeless.
