From fuel cell vehicles to self-driving cars, new technologies for next-generation autos are gaining traction.

In a move likely to accelerate this, the United Nations World Forum for Harmonization of Vehicle Regulations, which consists of major car-producing nations and sets international safety and environmental standards on vehicles, said in November it will allow carmakers worldwide to replace side and rear mirrors with camera monitor systems.

Following the U.N. panel's decision, the transport ministry will from June allow mirrorless cars on to the nation's roads.
