It is an important step for autonomous driving. The southern Chinese metropolis of Shenzhen is the first city ever to legalize autonomous driving in its metropolitan area and has developed innovative regulations to this end. Since August 1, they have regulated the commercial use of so-called intelligent cars. Since then, approved autonomous cars have been allowed to operate in large parts of the city without a driver at the wheel – in a metropolis of 20 million people that is one of the most densely populated regions in the world.
