Japanese automaker Nissan has recently unveiled its autonomous driving technology, tested in real-world urban areas. The company made a public demonstration, demonstrating the advanced capability of its self-driving vehicles to navigate the complexities associated with everyday city driving. Their initiative is seen as Japan's latest move towards its future vision for 'smart cities' with integrated technological innovations.

Japan is passionately pursuing advancements in technology, with autonomous driving being a significant field of interest. The society values convenience and efficiency, thus exhibiting high acceptance of such innovations. Public safety is a critical concern, with the government providing sound legal frameworks to ensure the safe operation of these vehicles.

In the US and EU, autonomous driving technology is also a major focus. While each region handles regulations and public trials differently, the emphasis on safety, public acceptance, and the technology's potential impact on traffic, urban planning, and the environment are universally shared concerns.
