The vision of a city of the future with self-driving cars at every intersection is taking shape in Shenzhen. The tech metropolis on the border to Hong Kong is set to become the world’s first major urban area where all major roadways, including highways, are open to autonomous vehicles without any restrictions. Two out of three draft reviews have already been conducted on the new set of regulations for managing smart, connected vehicles, according to city officials. The third and final review will take place in August.
