India's road transport minister expects to finalise rules for all cars to have six airbags by the end of the current fiscal year, as part of a series of steps to improve safety in a country that has the world's deadliest roads. The renewed push comes after Cyrus Mistry, the former chairman of Indian conglomerate Tata Sons, died in a car crash on Sunday, reigniting the road safety debate in the world's fourth-largest car market.
