The world’s largest experiment in driverless cars is underway on the busy streets of Wuhan, a city in central China with 11 million people, 4.5 million cars, eight-lane expressways and towering bridges over the muddy waters of the Yangtze River.
A fleet of 500 taxis navigated by computers, often with no safety drivers in them for backup, buzz around. The company that operates them, the tech giant Baidu, said last month that it would add a further 1,000 of the so-called robot taxis in Wuhan.
