The Financial Post reports in its Monday, Nov. 17, edition that major Western ride-hailing platforms like Uber and Lyft sketched a gradual path toward introducing self-driving cars at the Web Summit in Lisbon, with infrastructure, developing regulation and passengers preference for human contact weighing on the brakes. An Agence France-Press dispatch to the Post reports that building autonomous vehicles many times safer than human drivers is "almost largely solved," Uber's operations chief Andrew Macdonald told Web Summit attendees last Tuesday. He said, "Now what you have is a commercialization question." Lyft chief David Risher told AFP, "In five years, if autonomous driving achieves even 10 per cent of our business, that would be enormously successful." In today's terms, that would represent around $500-million (U.S.) of the just under $5-billion (U.S.) of gross bookings Lyft reported in its fourth quarter. That was a fraction of the roughly $50-billion (U.S.) reported by Uber for the same period, albeit on a broader slate of activities including food delivery. It expects to partner from next year on a Nashville project with Californian start-up Waymo and with Chinese tech giant Baidu in Germany and Britain.
