Chinese tech company Baidu announced Monday it can sell some robotaxi rides without any human staff in the vehicles.BaiduBEIJING — Chinese robotaxi companies are expanding abroad at a faster clip than U.S. rivals Waymo and Tesla — at a time when industry leaders say autonomous driving is finally near an inflection point.”I think robotaxi has reached a tipping point, both here in China and in the U.S.,” Baidu CEO Robin Li said Tuesday on an earnings call, according to a FactSet transcript. “There are enough people who have [had the] chance to experience driverless rides, and the word of mouth has created positive social media feedback,” he said, noting that the wider public exposure could speed up regulatory approval.His comments echoed similar notes of optimism in the last few weeks from Nvidia CEO Jensen Huang and Xpeng Co-President Brian Gu — who reversed his previously cautious stance after faster-than-anticipated tech advances. Xpeng is launching robotaxis in the southern Chinese city of Guangzhou next year.It’s a global market with significant growth potential, likely worth more than $25 billion by 2030, according to Goldman Sachs’ estimates in May.To seize that opportunity, Chinese companies are aggressively expanding overseas and claim they are close to making robotaxis a viable business, rather than simply burning cash to grab market share.In the last 18 months, Baidu, Pony.ai and WeRide landed partnerships with Uber that allow users of the ride-hailing app to order a robotaxi in specific locations, starting in the Middle East. Such tie-ups “will be critical to success” as they enable robotaxi companies to operate more efficiently and reach profitability more quickly, said Counterpoint Senior Analyst Murtuza Ali.Once we can generate profit for every single car in a second-tier city [like Wuhan] in mainland China, we can generate profits in lots of cities across the world.Halton NiuGeneral manager for Apollo Go’s overseas businessExpanding on experience at homeBaidu says that since late last year, its Apollo Go robotaxi unit has reached per-vehicle profitability in Wuhan, where the company has operated over 1,000 vehicles in its largest deployment in China.That means ridership is enough to offset a Wuhan taxi fare that’s 30% cheaper than in Beijing or Shanghai, and far below prices in the U.S. or Europe. Besides developing autonomous driving systems, Baidu has also produced electrically-powered robotaxi vehicles — without relying on a third-party manufacturer — that are 50% cheaper.”Once we can generate profit for every single car in a second-tier city [like Wuhan] in m …
