The time that cars could go completely driverless is coming "very soon", according to Jianxiong Xiao, CEO and founder of AutoX, a Shenzhen-based start-up developing autonomous driving technology.
Now, most regulations across various cities in China still require the presence of a safety driver in vehicles, but the company foresees that as more data gets captured over time, that requirement would be reduced, Xiao told CNBC's "Street Signs Asia" on Wednesday.
The autonomous driving tech firm chose to partner with Alibaba's AMAP—a Chinese mapping service provider—to roll out its RoboTaxi ride hailing service in Shanghai on Monday. AMAP is a "super mobility app" with almost 500 million active monthly users, according to Xiao.
AutoX had received support from Shanghai authorities to roll out a fleet of 100 autonomous ride-hailing cars in Shanghai's Jiading district in September last year.
Earlier this month, AutoX announced that it had set up an 80, 000 square feet RoboTaxi operations center in Shanghai to help facilitate(使容易)operations of its driverless fleet, as well as act as a center to collect data from daily operations.
Backed by investors such as Alibaba, Shanghai Motor and Dongfeng Motor, AutoX is one of the players in the trillion U. S. dollar Chinese autonomous driving vehicles market alongside others like DiDi Chuxing.
Xiao said they were working with the technology to ensure the vehicles were "very, very safe" and are carrying out a lot of testing.
Over a hundred vehicles have been arranged on roads daily to obtain enough data needed to validate the software and system, according to Xiao.
He added that the company was also running a hundred times more simulations(模拟)in the car every day, and the "huge amount of data" would help to prove that the vehicles could be used in "full safety".
"Our goal is not to just make(it)as safe as human beings, but going one step forward to really make…a superhuman safety standard; (cars)that(can)drive much safer than any human being ever, " Xiao said.

World War II began when the UK and France declared war on Germany, after German troops led by Adolf Hitler had invaded Poland on 1 September 1939 to claim land there as their own. Hitler had already invaded Austria and Czechoslovakia, so the war began over his plan to take more land for Germany.
The Siege of Leningrad is a famous event during World War II. For 900 days—from 8 September 1941 to 27 January 1944—the city of Leningrad in Russia was surrounded by German troops. That meant everyone inside the city had to stay there, and that there wasn't any way for food or other sources like medicine to get in. Many hundreds of thousands of people died during this time because there wasn't enough food or heating to go around, but the people who lived in Leningrad refused to surrender to the Germans.
In 1940, the French port of Dunkirk was the location of a big turning point for the Allie：in World War II. Hitler's armies bombed Dunkirk heavily, and many Allied troops were waiting on the beach to be rescued because they didn't have the resources they needed to fight back. From 26 May to 4 June, over 550, 000 troops were ferried to safety across the English Channel-the code name for this was 'Operation Dynamo'. Some British civilians（people who weren't in the army）even used their own boats to help save as many people as they could. The rescue operation helped to boost morale（士气）in Britain, where they really needed some good news. This helped in going into the next major event in World War II, the Battle of Britain.
June 6,1944 is also known as D-Day. On that day, the Allied forces launched a huge invasion of land that Adolf Hitler's Nazi troops had taken over. It all began with boats and boats full of Allied troops landing on beaches in the French region of Normandy. They broke through the German defences and carried on fighting them back through Europe for the next 11 months until they reached Berlin, where Hitler was then hiding.

Donald Kennedy would probably be amused by an old friend's tribute（颂词）to him as “very close to being a Renaissance man.”
It's hard to argue with the facts. The 8 years he served as editor-in-chief of Science was only the final chapter in a long and very exceptional career. He spent most of it at Stanford University, including 12 years as its president, interrupted by a 2-year head of the U. S. Food and Drug Administration under former President Jimmy Carter. But the Harvard University-trained neurobiologist wore those and other honors lightly, driven by a greedy curiosity about the world and a wish to help make it a better place.
Kennedy, who died on 21 April of COVID-19 at age 88, enjoyed his role as a scientist, educator, public servant, and communicator, recalls Tom Grumbly, who was his assistant at FDA. "A brilliant, funny, very special person," says Grumbly, who leads a foundation that claims increased support for agricultural research. "He could talk on any level to people about science, without placing himself above them. And he could stand shoulder to shoulder with the best scientists in the world.”
The combination of a towering intellect and a genuine concern for the individual served Kennedy well at Science. "He was a wonderful partner at the American Association for the Advancement of Science（AAAS）," says Alan Leshner, a former longtime chief executive at AAAS, which publishes Science. "He contributed his wisdom about science and public policy to our efforts on behalf of the community.”
As editor from 2000 to 2008, Kennedy led the journal through some high-profile（备受瞩目）controversies and quickly produced editorials（社论）on all matters affecting its readers. And it wasn't his nature to step backward.
In that 2008 editorial, Kennedy offered advice to Alberts, his successor, on editing a scientific journal. But it could also stand as an epitaph（墓志铭）on his long career in the public stage.
"Be as fair as you can, sympathize with anger, confess institutional error when appropriate, and be firm," Kennedy wrote. "And when the disappointed complain to members of the AAAS Board, remember to smile!"
1.What do we know about Kennedy from the first three paragraphs?
A.He worked at Stanford University after serving in Science.
B.He had a strong desire to make the world work for better.
C.He led a foundation to strongly support agricultural research.
D.He respected ordinary people but looked down on scientists.
2.What did Kennedy intend to tell Alberts in his advice?
A.Working for Science is not as easy.
B.Seeing the editorial work as a career.
C.Holding truth firm with a broad mind.
D.Remembering to smile while working.
3.Which of the following can best describe Kennedy?
A.Curious and funny. B.Amusing and greedy.
C.Crazy and controversial. D.Intellectual and caring.
4.What is the writer's purpose of writing this passage?
A.To honor Kennedy. B.To introduce a celebrity.
C.To remind us of Science. D.To tell a life story.
